Default Ac Not Blowing Cold

What are some of the solutions? MY a/c is not blowing cold at all anymore. Could it just be low on free on? Line messed up? Compressor seems to be working properly.

Check freon and pull codes first.

Worth checking the control module in the dash.

It is closest to the passenger side fender and door. The fitting on the kit will only fit the low side.

How can you diagnosis that this module is the problem? Is there a write up on how to get to it? Reason I ask is I think I may need to replace mine.

I'll bet that you need to charge it. You probably have a leak that needs repair.

It could be a few different things. If you need to add freon you likely have a leak. It will not go away. It seems one can will last a few months, it is good. DON'T OVERFILL. Then you add another can in one month, good again. On and on. Get a pro to sniff out the leak, many times it is a compressor leak. If the compressor is actually on with the clutch engauged and blowing warm it could be a relay or fuse as the compressor will usually shut down or cycle rapidly when low on freon. If a compressor you can get a rebuilt or new, could be a few hundred rebuilt, new at the stealership is $760 plus labor and with a recharge of R 134a added on. If you don't know don't guess, it costs more to replace wrong parts.
