Where to find motor blower resister for 1999 Chevy Malibu and how to change it?
Most of them are behind the glovebox on the heater enclosure. You may have to remove the heater control and/ or radio if that is in the way. The hard part is getting to it; they are usually held in place by a couple of screws and just plug into a connector. I hope this helps you. Mark
>>> Its behind glove box and behind blower motor its has cable divided from blower cable & cable to resister box, Its black box ( u can see cable going in ) attached with 2 screws , its behind blower motor towards front side
>> u have to remove cover on left passenger side ..
Remove the HVAC rear module auxiliary assembly. Disconnect the electrical connectors from the rear blower resister auxiliary. Remove the air outlet duct from the rear blower motor controller auxiliary. Remove the screws from the blower motor rear resister auxiliary. Remove the rear blower motor resister auxiliary. Replace the resister and install new thermal gasket.................
If the blower doesn't work on certain speeds, replace the resister pack, located just behind the blower, against the firewall. If the A/C light is flickering on and off, replace the AC head unit. If it's just the blower that's causing the trouble, passenger side. There are two pieces to remove to get to the blower. Then you just unplug the motor, remove the screws holding it and slide it out.
Remove the glove compartment. Its behind it just to the left of the Blower. Disconnect the connector with four wires on the bottom. Remove two hex head screws, also from the bottom. I used a 7/32 socket to remove them. Remove resister. The resister looks like a small circuit board with printed circuit traces on it. Install new resister in reverse order.
If you are missing some or all low speeds on the blower motor but still have high speed that would be the resister. The resister is located under the hood, attached to the HVAC (heating, ventilation and ac) box close to the blower motor. It has a removable electrical plug attached to it and is held in place with two small screws.
