No A/C Today
Compressor doesn't seem to kick on and the fuse in the fuse box is good.
??????? Blew ice cold last time I used it.

Re: No A/C Today
Did you run the diag on the AC head unit for error codes?

Re: No A/C Today
can also just pull CTSY fuse, easier than disconnecting battery. Will have same effect of resetting HVAC control head.

Thanks, Andrew.  My battery is relocated behind the passenger saet, so that helps tremendously. I'll do it in the morning. Hopefully, it will be that simple to figure out. Then, I need to figure out what caused it.

Re: No A/C Today
Well, you might want to check for codes in the control head first, before you clear everything by resetting it.
If it was working fine, and now is not, it either means you've had a catastrophic loss of refrigerant charge, or there's an electrical problem. Could be as simple as a bad low pressure switch (cycling switch), but probably need to get some gauges on the system before trying to troubleshoot further. |
