started up my bird this morning and i hear a low pitched chirping noise. i pop the hood with the engine running and a/c on, and im thinking the bearing/bearings on one of the pullies is going out. so i shut it off and the noise continues for another second or two. i suspect the fan motor is the culprit, as the fan keeps spinning after the engine is killed. again i fire it up, and shut it off, same thing.

has anyone experienced something like this?

i thought it was the fan. this is the SECOND time my fan has acted up on me this year. had to replace it once cuz the motor seized up the first time, and now this. luckily, i had a spare fan. now, here we go again. time for a new motor. dammit :(

ok, i supposedly ordered a new radiator fan motor, and i went to pick it up today and the motor looks different. even the connector is a 2 prong piece as opposed to the 3 prong one on the factory harness. the box even said "blower motor", so i figured its for the a/c blower, which isnt what i need. does this sound right with it having a different connector?

i also did a little searching and found that the ircm's are prone to fail. can a bad ircm cause motors to lock up?

No if it's the right motor it will be the same connector. Or it will at least come with a pigtail to adapt it but nonetheless it has to have 3 connections as it is a 2 speed motor. I think you are right they gave you a blower motor.

And a faulty IRCM probably wouldn't cause the fan to fail. If the IRCM failed and got stuck on or something, the fan would run all the time. An overvoltage problem or something of the sort would be caused by the charging system.

dagnabbit? sounds like a word my grandfather uses :tongue:

chris, it turns out it actually was a blower motor. so for chits and giggles i went to autozone (initially i was at o'reilly's) to order one. i thought
maybe they would have a picture of the right one. lucky for me, they had a fan motor in stock. i bought it, installed it, works great, and mike is happy.

and get this. the box for the fan motor does say radiator fan motor, but it and the box for the blower motor have the damn part number and manufacturer. weirdness.
