My blower fan on my AC stopped working on my '92 Ford Explorer. I checked the fuse under the dash and under the hood. Both are OK. Any quick fixes available or do I have to replace it?

under the dash, there is a small oval shaped piece of metal with 2 1/4 inch bolts holding it on, and a white plastic plug in the middle of it! It is a High/low blower switch and could be bad! But check your fuses first to maake sure they are not blown! In the fuses under dash and under the hood there should be a fuse for blower motor!
you probably blew a fuse that fan has its own fuse believe it or not. look under driver side dash or left side of dash for the fuze box the fuses should be labled
This happened to me and I tried everything to fix it before having to get a brand new main blower motor. As soon as I replaced it my air started to blow again and problem solved
it should be in the fuse box under the hood or you may have another small fuse box under the dash ,check all your fuses,if they are OK the blower motor may be faulty or the switch could be the problem.....hope this helps.....cheers
Ok, first off, check the fuses under the dash. If they're all good, does the blower work only on high speed? If yes, then you have a bad blower motor resistor, which is located under the hood, near the blower motor itself. If the motor doesnt work at all at any fan speed, make sure the wiring harness that plugs into the motor under the hood is clean and tightly installed. If it still doesnt operate, sometimes tapping on the blower motor housing will kick it on, but if that doesnt work, you may have to replace the blower motor. They are available aftermarket, and arent usually too expensive.
Ok quick fix........ This is a common GM problem. The heater will stop operating when the plastic vacume line is broken under the hood. It is an 1/8 inch black plastic vacume line running fron the intake manifold to a vacume check valve under the hood to the heater/AC assy located to the passenger side. You may also want to check the fuses under the dash to the blower motor. If the fuse is good take a Digital multi meter and check for voltage at the motor. If there is no voltage check the reistat in the blower hosing. It is a small rectangle plastic piece on the blower housing with two small screws. Check for voltage at the input and output side. If there is voltage check for resistance at the motor by unpluging the blower motor and probing the terminals to the motor. Tap the motor and see what type of fluctuation you get. Lastly if all that checks out and you have no voltage to the motor or reistat check the switch input and all three fan speed outputs. It could be a simple switch issue. Good luck and let me know if you need further guidence.
