Fan Blower Motor Problems

Hi, ive been reading and searching the forum alot but i cannot find any answers for my problem. I have a 2006 ls coupe 2.2l and the blower motor works on and off. Ive checked fuses and relays, they are all good. Ive noticed the connector for the blower motor is loose both where it plugs in and the wires inside. Ive wiggled the wires and connector and it works on and off until i hit a bump or sometimes it just turns off. Any one have any ideas? It is truly a PITA dealing with it. Again when it wants to work the fan settings (1-4) work great, it blows cold or hot depending on the setting. It just doesnt want to play nice all the time. Any help you guys can provide would be greatly appreciated.

Btw the wires in the connector look to be exposed for 1/8 inch and semi corroded(ie not shiney copper anymore)

You seem to be talking about the fan speed resistor network located at the bottom of the heater box. You will need to replace the resistor network to fix this.

Uh replace everything or what? Cuz everything works if i fool around with the power connector for the blower motor. The resistor should be working if it turns on and operates from 1-4 after i found the spot the power connector wants to work at, right?

Just pulled the power plug and it looks a little melted on the upper wire on the female connector...

Sorry man but these do fail and the only solution is to replace it. I know GM don't give it away, but sometimes you just have to bite the bullet.

It actually wasnt the resistor. Just got one from oriellys plugged it in and nogo. Then i tried jiggling the connector that runs from the resistor to the motor and boom turned on. Any clue where i could get a new connector?

Sounds like a short to me. Is it actually by a connector or is it in the middle of the wire somewhere? Also, I saw you post that something looked a little burnt, anyway you could post a picture of that?

Might just be a broken wire at the connector.

Yeah ill try to figure out how to post something with my iphone. The connector that runs from the resistor to the blower motor itself is semi charred. Im thinking it could be a short too since the wires are a little exposed at the base of the connector. Ill post a picture in a few hours after i get done working. Oh one quick question the emis fuse, a red 10a next to a relay in the fuse box under the hood, if it were blown could that give me a few cels?
