Climate control problem

2004 v6 ex, quit blowing cold air, took it into the shop, system is charged, no leaks, can engage compressor with jumper. Power going to fuse box. Shop thinks PCM has failed. Took it to the dealer they said same thing but cannot verify. Anyone heard of this?

could the system be overcharged?

Had the same problem in my daughter's 99 accord. It ended up being the heating/AC control panel. Some of the lights on the panel weren't working. $50 later and a quick stop at the junk yard, the problem was fixed. OBTW, Honda wanted $200 for the control panel. Do all the lights on your control panel work?

Shop thinks PCM failed!?!? so quick to jump to that.

the fan does blow air though?
it could be a stuck air temperature blend door, or a restricted evaorator core.
pluse many more things.

maybe if you were a bit more specific with what works an doesnt, we could help you out more.

Also, when there is a fault with the a/c system, its federal law that the HVAC unit will adjust/default to heater mode.

Hmm, in my car, the passenger side will not blow warm or hot air, it is always cold. Needless to say, it is hard on my passengers during winter.

Does this mean I can get Honda to repair the climate system free of charge due to this Federal law?

Wishful thinking, but I seriously doutb it.
