Blower Motor

[JonJon68]

Hi everyone. I'm going to drop my blower motor tomorrow to replace my defective resister. While I have it out, I need to lube it. Question is, what's the best lubrication/grease to use? TIA...

Use a light oil (3 in 1) works well and put it where the shaft enters the motor. You may have to remove the fan from the shaft to get to it but it shouldn't be hard to do.

Thanks GTP. I already have the kicker panel off and my back is looking forward to being "twisted" for a while.

If you haven't done the work yet you can save your back from undue stress by removing the passenger seat. Gives you a lot better access and it doesn't hurt so bad! (the voice of experience.)

Yea, I've heard that. I haven't done the work yet, too windy and cold. Supposed to warm up later this week so I'll give it a shot then. Fortunately, I don't have any back problems so I may just take a stab at it without removing the seat. Is it difficult to remove the passenger seat? I haven't looked at it yet. The motor itself is easy to get to but I'm a little concerned about how tight it is to get to the resister. Note: I called the dealer and they wanted 59.75 for the A/C Delco part. I purchased mine from rockauto.com for almost half that and it's a A/C Delco. Saved 30 bucks there.

Good move purchasing the part from Rock-auto. The seat comes out easily, just two bolts in the back then lift forward. If you have an electric seat you will need to disconnect it. You may also have to remove the seat belt bolt. I did the job with the seat in and found it difficult to get to the area. With it out it is much more comfortable and worth the hassle factor of removing the seat. Believe me your back and neck will thank you!!!

Also remember to remove the seatbelt from the side of the seat. When removing the seat,recline the seat back as far down you can, this will make it easier to be able to remove the front mounting tabs. Then put the seat in the upright position, makes it easier to remove the seat from the car.

I got r done last Saturday and took about a half hour. My back is in good shape so I left the seat in. It's a easy replacement just really tight. Thanks again for all the advice.

My back has seen better days so that is why I have my seat pulled out. It makes it so much easier. I think that it might be my blower motor that caused the resistor and the connector to melt. I am going to pull the blower motor and see how much current it is actually pulling. Glad that you got your done. I just got the connector housing and I will be fixing my this weekend.

I have a 97 Grand Prix and I replaced my defected resistor about a year ago with a brand new and "improved" one from the dealership and it has already died. What has caused this to happen already? Only speed 5 works...

Did you notice any water in the heater box when you replaced the resistor? If not, then your blower motor is probably drawing too many amps, causing the resistor to overheat and fail. If you did have water, check the cowl seal around the air inlet, and install a cabin air filter from a like-year Buick Regal (the spot is there, but GM never installed one in the G-Prix). This will help seal the system better against moisture, and protect the blower motor from damaging dust and debris.
