Blower motor went fzzzztttt...

[Corwyyn]

OK, I'm not sure it's the blower motor so I'm asking for input from the knowledgeable KJ Country core audience. Driving home from the doctor's office last week and went to turn the fan up to get things cooled off. Turned it to #3 and about two seconds later it went dead. Tried all four settings with no joy, figured it might be the dread resistor block. Next day went down to the dealer and procured said resistor block and set about replacing it. After it was installed I tried the fan and still nothing. Came inside and read some more, went out and did some more tests. This is what I have done so far:

Replaced resistor block - no joy.
Checked fan switch - all settings read good according to the test from the FSM.
Checked blower relay in junction block - good.
Checked 40A fuse for blower motor - good
Checked for voltage at relay - good.

One thing I didn't do but will try tomorrow is to pull the switch connector to verify it has voltage coming in. So can anyone think of anything else I might have overlooked? Right now I'm leaning towards it being the blower motor itself but I want to make sure I've checked everything else before I go thru the hassle of replacing it.

sounds like the problem i was having, i did exactly as you with the same results...

... just for fun, check the wires going to the fan... jiggle them while you have the switch on for it to blow... for some reason mine were loose?? and i just played with them a little and it started working... odd, i know....

Kevin, I had that happen... dealer replaced blower.

Yeah, unfortunately the recall on yours only covers '05-'06 MY, mine is an '03 so I'm s.o.l. on that one...

Check for power at the connector and if you have power there then it must be the motor.

Thanks Blake, that's something I didn't do. Went out and checked it just now and there is 12V at the connector so I guess it's time to find a blower motor. I'll just make sure I take plenty of lubricant when I visit the dealership.

I checked out the price at the link below and it said its $143. It says its for a 02-04 liberty so I guess those are the same.

Edit: Did you turn the knob while reading the volts to make sure it changed?

 

[Corwyyn]

I didn't turn the knob but I had checked the switch to make sure all four connections had continuity and I had replaced the resistor block - figured as long as I was getting voltage to the connector I was good. Called a local dealer and got a price of $150, cheapest I found online was $110 at http://www.chryslerpartsdirect.com/. I'll go to the dealer tomorrow and pick the one they have up since I really don't want to wait for delivery, and by the time I add shipping I won't be saving that much...

Went and picked up the blower motor today, it was surprisingly easy to swap out. I have some errands to run this evening but later on I will do a quick how-to for those who are interested.

Mine happened brfore the recall....

So I take it the motor was the problem?

Got any pics? I would like to know where its at and such.

Yes, and yes. I'm getting ready to leave for a while but I'll post pics and such later tonight.

Glad you got it all fixed up then.

OK, got the how-to posted. Should be easy enough to follow, but if anyone has any questions let me know.
