had a new ac compressor installed in my car yesterday however the tech told me that the ac control unit is crapping out. I was finally able to get the ac going after turning it off and on several times and restarting my car. To add some more details everything on my screen indicates that it is getting power (the lcd screen shows on, the lights in the ac button turn on) but the ac fans are not coming on.
Ive read in other post that resetting your battery can fix this and will try it when I get home today.
Any other ideas or suggestions or just I just replace to whole ac unit control ?

 

Check the pressure sensor on you condenser, if it dies it could cause issues. I tested mine out when my compressor clutch stopped engaging, but couldn't figure anything out about it, other than that the fans kicked back on as soon as I plugged it back in. If you unplug it to try to jumper the contacts of the plug, don't jumper the 2 outside contacts to eachother, just trust me on it.
