So my blower motor has been acting up since last fall, it would randomly cut out at any of the 4 speeds, and then randomly come back on. Well the other day it finally quit and hasn't come back on. I played with the wiring connections on the back of the climate controls but it was no help. Guess that means its down to the motor, the switch, or the climate controls itself.

I'm really hoping it isn't the blower motor. My Haynes manual says that to replace it I have to remove some of the AC equipment, which means evacuating the system, and then having it refilled.

Anybody have any advice on this issue?

 

The switch on the climate control does seem to love melting for whatever reason lol. And the blower motor was very easy to do on my jeep..10-15 minutes tops. However, I do not have abs, and the ac system on mine is non existent other than the compressor so I'm not sure how much it's presence complicates matters

 

I would check the connection at the blower motor itself. Maybe the plug is backing out. Kinda seems like a loose connection or this sounds like a blower resistor problem and is much easier to check and change then the blower motor. Pull the resistor and see how bad it is. The coils are probably corroded and rusted away.

You are correct about the blower motor replacement. With AC, you have to remove the freon, remove the accumulator, replace the blower motor, put a vacuum on the system and charge the freon back in. Sucks but there's no way around it.

 

Thanks for the advice. I pulled the resistor and it didn't look too bad, I went ahead and cleaned it. I was talking to a buddy of mine who suggested whacking the blower motor with a hammer to see if it would fire up. I thought he was joking at first but he said that like starters you can smack a blower motor with a dead blow hammer because they aren't completely fried yet, and this is a great way to tell if they are bad. So after removing the resistor I decided to give this a shot, and wouldn't you know it the motor fired right up. It now works on all four speeds, but that's temporary. I clearly found my issue, and I'll need to replace my motor.

My Haynes manual suggests only loosening the connections on the accumulator and pivoting it out of the way of the blower motor. I assume this is so you don't open the system and have to replace the dryer? How much should an evacuation and refill of the system cost? I assume I can't empty the system myself legally?
