My a/c is doing the same thing. If that fixes it and it's easy that would be awesome. I really don't wanna go spend a bunch of money to have someone else do a pretty easy fix

 

Does the blower speed resistor live in the ductwork behind the glove box? Where the cabin filter is, or nearby?

 

When the resistor fails, it fails completely. That being said, if your blower switch has four positions (and that would be four individual resistors), 1,2,3, and 4, you would probably find that nothing works except for 4, or missing lower speeds. Generally, the highest speed survives, but the lower resistors fail in order from the lowest going upward. Sometimes they fail because debris (leaf particle, etc.) get caught in the resistors (which look like springs). The "resistor" is actually an assembly with 3 or 4 spring-like resistors.
If you have a high mileage vehicle, the blower motor itself might be drawing too much current, which would make the resistor fail all over again after you replaced it. Or- the blower might have debris (leaves, mouse nest,. etc.) jamming or gumming it up, resulting in higher current draw... (but that would explain the noise when the blower is on HIGH). Luckily, the blower resistor is usually cheap, and easy to put in. I have replaced them in a Chrysler Town & Country, and a Jeep XJ Cherokee. A 15 minute job in those cases.

 

I have spoken to a mechanic today and he suggested to me that it looks more like the blower motor may be the problem as the blower got louder and in lower settings doesn't blow as strong as it should.If the resistor failed then the fan would stop working completely or would work only at the highest setting. Anybody can comment on this? Than you.

 

Yes, the resistor is located next to the blower fan , to access it you need to remove the glove box door [ by squeezing it - I never did remove the glove box it yet but that's the way it supposed to be removed] , it seems to me now it may be actually the blower fan itself.

 

If you think it is the fan motor, might try a little WD-40--or similar on the shaft(s), once you get the fan ass'y out, it just might be gunked up and needs a little chemical TLC, and probably is a lot cheaper than a $50 +/- fan motor.

 

Jack you may be right

Jack you are probably right. A mechanic checked it out and said to me that it looks like the fan is giving up. I'll keep it running till it gives up and then I should be able to change it myself. It's not an airplane and a vital part so it can wait. Thank you.
