OK, so this is kind of weird. My AC compressor works - when I send power to it turns on and the AC gets all nice and cold. But when I press the AC button, the relay doesn't click, and it doesn't turn on the compressor. I was told this was due to a faulty ECU.

Also, if I use my remote entry to unlock the doors, it blows the fuse. I was told this too was an ECU issue. I've done a little digging and right on top of the ECU is a little box that says something about lock remotes and alarm systems. Could I just replace that? Or would that throw a security flag just the same as if I tried to swap ECUs?

Would getting a new ECU fix this? Or could I just get it reprogrammed? What do you guys think?
