A/C problems :-\

[el_conquistador]

Okay, so the other day my mechanic changed all the seals in my A/C system and also put in a new evaporator. Checked for leaks and found none. Recharged the system and returned the vehicle.

Got it back on Friday night and the A/C worked great until this morning. Driving down the road and switched the lever over to "defrost" for a few minutes and then tried switching it back. The light stayed off indicating that the A/C was on would not light. I pushed the button on and off and still nothing. The blower is working fine but the light won't turn on and the compressor doesn't kick in now.

Got home tonight and changed the fuse that controlled the switch and still nothing. No cold air.

Any ideas would be helpful. This is on my 94 Ranger 4.0.

mine does that sometimes, but I just turn all the switches off on the A/C-Heater controls, and turn the vent knob to max a/c, then push the fan knob to turn on the a/c compressor, then turn the fan on. but you may have already tried that, just my 2 cents

Yeah I tried all that too.

Check to see if you have power going in and out your cycling switch which is located on your accumulator. If you bypass your switch with a jumper wire and your a/c compressor turns on then it could be a bad switch, too high pressure or too low pressure.
