Blower motor problems


If ,and when,your blower motor has problems,and it will not blow on the low speeds, consider the blower resister,it is what controls the speeds for your blower motor.Now,replacing the blower resister is the thing to do,but two things to check for also,,the connector to the blower resister,and to the back of the fan select switch,the one you control,on the dash.These connectors,including the fan switch can be burned,and need replacing also.Now the reason these go out,and burn,and melt the connectors,is,that the blower motor is pulling too many amps,even though the blower motor runs great,and sounds good,trust me,the blower motor is the reason,so replace all of these parts when you replace the resister.If the connectors are fine,and the blower switch is fine,of course they will not need to be replaced,but the blower motor is a must,or you just might have to do it all over again in a few months,along with the switch,and connectors I mentioned.

1990 Cadillac Eldorado cabin fan not working fuse and relay changed out what is problem


Might be the Resistor pack located close to the blower. It has a flat connector with 4 or 5 wires, and two small screws holding in the duct. It may be a crispy critter. It happens... The blower moves air across it to keep it cool. The blower motor may be bad as well, or possibly the fan speed switch. May very well be the fuse for the blower as well. The blower connector may be loose. Let me know what you find.

I have changed the resistor and the fan switch on a 1997 jeep 4.0 wrangler, but only the high fan speed still works. what else could it be.


Sounds like its a bad blower motor connector,Find blower motor connector and perform a wiggle test while turning fan switch up and down.Also look at connector for melted wires or the connector itself.Hope this helps!!

1998 GMC Sierra. Blower motor works sometimes. No particular circumstances, just when it wants to. Checked all fuses, relays, even replaced the resistor, nothing. Followed the wire harness and found...


could it be the blower motor it self? sometimes they have a "bad spot" when it is not working, can you hit it and make it run? pretty common on these trucks. the switch is also common. they often melt at the connector on the back making a bad connection. i would double check the motor first.

1997 jeep wrangler se,fan for a/c and heat quit.all fuses seem good.any other relays or switches jeep have had probs with?


If it only works on Hi, then your resistor is blown. If you can pull the connector to the blower fan and use a voltage tester to find voltage there with the fan switch turned on then it's the blower motor. If there is no voltage there, then its the switch on the dash. Usually the resistor and the switch only die because the blower motor is about to die and is pulling more current then it's supposed to. Change the blower motor too if that's the case.

A/c heater won't blow... Blower works even replaced with new blower but still won't blow... Is there a relay to replace? The fuse for a/c is good


did you check to see if the a/c belt is still on the a/c puller ? if so then try a flush of all hoses.

How do i change the fan switch on a saab 900s 1989? can someone help me out here


Are you talking about the a/c fan/blower switch?
Remove the glove box and the panel from the side of the center console.
Remove air duct on floor and protective cover. Remove the 2 fan control unit retaining screws and unplug the connector. Hope this helps....if you did not mean the a/c fan/blower switch please re-post with more specific details.
