Your ac quit blowing 1995 Chevy van?

Answer 1

You need to provide more information..do you mean the blower motor quit blowing out air? Or does it blow out air, but it's not cool? If the blower motor quit blowing out air it could be the switch, short in the wiring between the switch and motor, fuse, or the blower motor itself. The obvious is to check the fuse first. The second would be to unplug the wires to the blower motor...using a voltmeter...check at the wiring coming from the switch and see if it's receiving 12 DC volts. If it's getting DC volts..the motor is probably bad. If the blower motor works, and there's no cold air at all when you first turn the A/C on, then check the compressor leads to the compressor and see if it's receiving 12 DC volts....also check the fuse first. If it's receiving 12 DC volts, but when you turn it on...the clutch on the end of the compressor does not pull in...then it's probably the start windings on the compressor...however..make sure the A/C has not been run for awhile because the compressors have a thermal limit inside the compressor that will turn the compressor off if it overheats to protect it. On occasion, these limits are defective and cause the compressor to not come on either, in which case you have to replace the compressor...they are internal. If the clutch pulls in...but it's not cold air within a few minutes...buy a kit at Walmart or auto store which has a pressure gauge and connect to the supply side hose coming off of the compressor (the gauge end will only clamp on to the correct one...it will not fit the high side liquid connection). Blue and mid yellow pressures are good...less or more are bad. If it's less...buy a fill kit with R134A and add freon to the blue mark. Good luck
