I took a chew one of the few mobile technicians in the country that I trust and this was Don‘s mobile RV service with a winner in Lakeland and lives in Akron and we looked all over we had a new switch that we bought as my rigs at 2018 we bought the control panel that’s in the front of the dash put it in same problem. Opened up the hood trace the wire like many things in an RV the wire had come off had disconnected.
I was pretty upset that Ford general RV Goodyear couldn’t find a simple thing as tracing the wire to the top of the thermostat for the AC. So now I have an extra switch and air-conditioning.
There was a post that talked to about the panel in another post. Again it was a simple wire that it fallen off and then those other forms it’s always just one wire. Best of luck

An A/C shop would have found/fixed that issue in 15 minutes. Experts are experts for a reason.

I am not sure why you commented on the post that an AC expert would solve the problem. Everybody has an opinion. I had the problem and took it to three experts. Perhaps the fourth expert solve the problem as he had the information from the previous three experts.

My blower quit some time back. Turned out to be the fan fuse. 5 amp, under the dash.

The ProAir AC unit is not a Ford Chassis product. Already had a similar problem. In my case it was a crimp in a clutch wire that came undone. Had to find it myself and point it out to my La Meza rep. He too tried telling me it was a Ford problem. Verified with Ford and then Thor that the ProAir is an add on by Thor.

Check you clutch for engaging first and then go from there with the dealership.

The last time I tried to book a warranty appointment with Ford, the closest 'truck center' was 200+ miles away and a 6 month wait.

You have to take it to the correct expert.

A Ford auto/truck dealer service department is not an A/C expert.
A Goodyear Tire expert is not an A/C expert.
A general RV repair expert is not an A/C expert but luckily; you got one that spent the time to find and resolve your problem.

An A/C repair shop IS an expert on all automotive style A/C systems and have traveled down the diagnosis/repair road that you would have presented hundreds of times, saving you much time, frustration, and money.

A/C easy quick checks.

Check compressor running? Look at compressor clutch for emgagement with a good flashlight. If not engaged, multiple reasons for it.

On mine, had issue wth no cooling after hittimg a bump/pothole. Turned out crimp style push on wirr comnector had loosened. On v10 vegas is on left side engine compartmemt behind hood. I tighten push on part every time I change oil. No more issues. Is high pressure switch and looks like old oil pressure sending unit. They let wire dangle and it seems to loosen push on part of terminal. Lot of stuff in area like air inlet hoses so I just tighten instead of reroute wire.

After reading a bit on the forum, it sounds like nobody knows what is causing this (at least that was the case 6 months ago) so I opted to not make the long drive and wait until I did some suspension mods (Sumo springs, new shocks, stabilizers) to see if it made a difference, since this error appears to be traction related. It does seem to happen less frequently, although does still occur on occasion.

I don't think it would have mattered what I was booking for; my experience has been that all Ford and all RV shops are extremely backed up. I also looked for an AC shop near me, per the advice here. None of them would take an RV. They said they need wiring diagrams and don't have the room (I'm in Santa Cruz, CA). I finally found ONE shop out of 10 that is willing to try to diagnose... the fact that I get zero cold air has me hopeful that the compressor isn't on, and it's a wire or switch or fuse that we can find... (and not at all surprising given the lack-of-quality workmanship I have seen on my Thor 25.6)

Given the lack of shops that are willing to take an RV, my next step after that is to call the couple of RV repair shops in town, and the closest Ford truck dealer. Beggars can't be choosers; has been very difficult to find anybody who will look at all.

Thanks again for all that have contributed... it's great to have a place to go to ask questions and commiserate with fellow RV owners.

Torque is a free app.
A obd2 Bluetooth dongle is $12 on Amazon.
There is a very good chance those two things will clear that code for good.
And
Torque will tell you a hundred other things like fuel mileage and gallons in tank and ambient vs intake temp and distanve till empty....

Thanks, probably good to have for other reasons, but the 'Advance Trac' error clears itself every time the vehicle is turned off, so clearing it is not the issue; it re-occurs.

Even when it's clear, it eventually comes on again, and when it does, it disables the cruise control, so either I need to pull over to turn the vehicle off/on, or drive with no cruise.

Sure, so next time you have a lawnmower problem take it to the Ford dealer and pay their $200 diagnostic fee.

Ford doesn't make the subject RV AC system nor did they design the electrical control. They are not the expert.

He might not say it, but I will. He is

I think the thread may have got off to rocky start because it is hard to read others personality just by reading a post. Things can come across the wrong way at times. But in this situation, I really do believe that if you give it time, you may come to learn those who can / will help you the most. Keep reading and I think it becomes clear. I like your moxy. It is kind of nice to be able to ask about all kinds if things, but be prepared for straight talk, many on the forum (not me) have been there and done that having seen the same rodeo like Groundhog Day for years

I am not about to get into the A/C debate but let me say a few words about the OP's Service Advance Trac error:

This error occurs on many Ford chassis, not just E350, E450 and F53s but on the Ford Focus passenger car for example. I have followed most of the RV threads and one on IRV2 goes for hundreds of posts and no one knows for sure what causes it, certainly not Ford. One good piece of advice is to look up the NHTSA website and post your problem. You will need your VIN. More complaints may get more Ford action.

For me it is a minour annoyance as I don't use cruise control and as far as I can tell, the wind stability control does nothing, Advance Trac on or off. So I ackknowledge the error by hitting the steering wheel button and the next time I stop and turn the engine off, it clears the error for anouthe 50-500 miles.

FWIW, I think the problem is the clearance between the tone ring sensor and the tone ring (a serrated gear looking device on each axle). One guy reported filing down the sensor's base to get it closer to the serrations solved it. But he is one out of many, many more.

Once Ford finally figures it out they will probably issue a recall. I am waiting and hoping for that.

Hello All,

I thought I would post an update to my original issue, in the event that it's useful to others.

I think as I mentioned, none of the AC expert shops wanted to take on an RV here in Santa Cruz - they don't have wiring diagrams, don't know their way around RVs, and frankly don't have the space. I did finally convince one shop to troubleshoot, and after 1.5 hours, their claim was that there were 2 AC lines rubbing against the frame that punctured, and emptied the system. "we don't know where to order the hoses, and we don't have the freon to charge that system". Find an RV repair shop" was their advice.

(BTW, I did send them the HVAC service manual I found on the Thor site - the system is made by Evans Tempcon Inc, so it's not quite Ford, and not quite like other class A designs).

I am now at the RV shop. The first feedback I got was "those aren't AC hoses, they have hose clamps on them, they're water, but still need to be replaced". And the owner of the ship hates my Axis because it's a class A build on a class C chassis and it's nearly impossible to get at anything under the hood. He also said it's a standard charging setup and the AC shop is full of BS, so it's a "he said, she said" situation.

I'll follow up once I have more news, but so far what I have learned in that, at least in my area, an RV service center is probably the best place to go, and I continue to be extremely disappointed with the quality of the Thor Axis - I have seen a ton of really shoddy workmanship...

If your coach is out of warranty, the best place to start is with an independent RV repair shop for most things. If it is a chassis A/C problem, go to a truck or car shop that specializes in dash A/C. These places survive on previous customer recommendations, so they are good or out of business. Let me also praise the mobile RV repair technicians. Most are really good at trouble shooting because they work in every kind of RV for tear-drop trailer to tag axle pushers. I have three occasions to use them in my 34 years of RVing. Completely satisfied in all three occasions. There are a limited amount of repair places when you need a part in Creed, CO. I is a good piece out to Walsenburg and back. The fishing on the Roi Grande was to good to leave for gas valve.

Thanks for the update.

Howdy everyone. This is my first reply since joining the forum. I'm very impressed by the knowledge and helpfulness of members.

I purchased a new Thor Windsport 29m on April 23rd. One of the 1st things I noticed was no cooling from the dash air. Gave an 18 item punch list to the dealership, which to this day is only half completed. I was told by the dealership that the A/C unit needed to be looked at by the local Ford big truck dealer, and that they would set up an appointment. That never happened so I made it myself. I took it in yesterday morning at 8AM. Sat there 3 hours before it was even brought in. Turns out it had no refrigerant in the system. Ford is saying that it is Thor's responsibility because Ford only hangs the compressor on the F53 stripped chassis for class A motorhomes. This is because each manufacturer has a different dash layout. So, Thor was responsible to complete the system, therefore holds the responsibility for the warranty. Quick end to this story...Thor is pointing fingers at Ford and Ford is pointing at Thor. Bottom line...paid for it myself and filing claims with both firms. Isn't the whole point of RVing to relax???
