'97 Grand Prix GT Blower Motor Resistor
Hello everyone, my A/C system has been working for a year only if I set it to the highest speed (5) and any other speed will result in the motor not working and the A/C orange light on the dashboard will stay dimmed; as far as I know this happens when the motor resistor is blown, but today I arrived home and I was turning the Speed Knob to the OFF position, as I changed between every single speed the motor was still working and decreasing the speed, everything was working fine until some minutes later when I checked again, the lower speeds wheren't working again. What do you guys think?, I checked the resistor's connector and is fine.
Best Regards... |

The resistor is going out and needs to be replaced. It is possible that it is somewhat intermittent and that it why it started up again but it is on its last legs.

One thing when you do the blower motor resistor, take the front passenger seat out. It will make it so much easier to take the resistor out and to put the new one in.

Re: '97 Grand Prix GT Blower Motor Resistor
another couple of tips.
1. take the blower motor out to make access to the resistor easier. It's only 3 screws and trust me, it's worth it. 2. the back two retaining screws are very hard to get at. The 2 back holes in the resistor are slotted, so only the front screw has to be removed to get the resistor out. The back 2 only need to be loosened slightly, then slide the resistor forward to pop it out.

Re: '97 Grand Prix GT Blower Motor Resistor
I have one question on the compressor bearing, is it internal or external. So it does sound like the bearing is starting to fail on the compressor.

Re: '97 Grand Prix GT Blower Motor Resistor
Hello I have no idea about the internal or external ring. I have noticed that the car will sometimes blow very cold air and not so cold air when the humming sound is more noticeable. Could you please give any more details about the internal or external bearing?, also could this be a clutch problem?.
Thanks for our help. |
