I bought a Auxmod basic a few weeks ago. I installed it and it works no problem. But when I hooked it back up and turned my car back on the heater contorls didn't work. The blower speed control still works but nothing else. I took my headunit out and checked the connections and I couldn't see any damage. Any suggestions on the next step? Thanks

I get this from time to time. Dont know?

 

Search for a thread on repairing the solder points on the heater control circuit board. I believe I am having this same problem.
