Bienvenu mon ami. Your English is much better than my French (you saw the extent of my French in the first three words). I suspect you may have to take the dash apart to get to the blower motor. I think the 2015 Vegas has the flip out computer table in front of the passenger seat as do many ACE coaches......so there may be similarities in the dash construction and removal. I did a quick search and canít find much except there is a link attached talking about blower motor replacements in some ACE coaches......but no details or pictures. The last three posts on the link say they have done it, so you could try sending them direct emails through the Forum to see if they can provide you with more information. Maybe they (or someone else) will see your post and respond with some pictures and a detailed procedure. Bonne chance.
