Hello and welcome!!

I will be happy to assist you, first i will need to know if the climate control system is automatic or manual.

how many miles on the vehicle?

Possible causes a open fuse. The blower fan can draw too many amps and cause the blower fan resistor to fail. If this occurs i would recommend replacing the fan and resistor.

So the air conditioner stopped blowing cold air?

from your first post it sounded like the a/c fan stopped running.

Expert:  Derek Werner replied 1 year ago.

This could be solved as simple as disconnecting the negative battery cable for 20 minutes. This procedure will reset the on-board computers and force the A/C system into a self learn mode.

Also a refrigerate leak in the a/c system will cause warm air from the vents.

With the a/c turned on can you hear the compressor run?

Try looking at the compressor clutch to see if it is engaging, and the engine cooling fans should be on as well.
