This 1992 Buick Park Avenue came in with the complaint that the blower did not work. Customer also stated that the blower motor had been replaced about a year ago. The blower motor is located in the center of the firewall under the hood.
The first thing that I found was that the blower motor harness connector and the terminals in the blower motor were heat damaged, burnt. I had also noticed that the harness connector showed significantly more damage that the blower motor terminals. Diagnosis of faulty connector and motor assembly.
I replaced the motor by removing the mounting screws and pulling the motor assembly from the HVAC box.
Next, I spliced in a new harness connector assembly. To order a new repair harness please click here.
Installed the new blower motor with the oxygen sensor wire caught under the motor. Of course I removed the motor and put the wire back where it was supposed to be.
As shown in the following picture and connected the new harness to the motor. I cannot stress this next point enough. The only reason the blower motor that was installed only a year ago failed was because the installer failed to replace the connector at the same time. ANY time a burnt harness connector is found it and the component it attaches to must be replaced at the same time or early failure will occur!!!!!!
Thanks, couldnt figure out where it was, and this helped.
