Fuse keeps blowing on AC thermostat

[VanVFam]

AC was working fine. We took it in to have the gauges rewired (black tank gauge was reading the contents of gray and vice versa). When we got it back, each time we try to turn on our AC the 2Amp fuse in the thermostat blows, and the AC will not turn on. We replace the fuse, the AC turns on, then immediately the fuse blows and the AC shuts off again. Any ideas?

Sounds like they rewired more than the gauges. Probably a short in the wires or the crossed something they shouldn't have messed with. Might want to take it back and have them fix the issue.
