Blower Motor Resistor Replacement Pontiac Vibe AC Heater

Описание: I replace the resistor and the electrical plug for the blower motor on a Pontiac Vibe 2002-08. The bad plug was causing an intermittency problem (the blower would go on and off sporadically, such as when I went over a bump in the road). Not long after this intermittency problem erupted, the resistor failed and, consequently, the blower motor only worked when the heater or AC was on high; no air on low or medium setting.

Removing the resistor can be frustrating if you don't have the right tool. I'm using a 1/4" swivel tip socket and a 1/4" screwdriver type of driver, purchased at Harbor Freight:

The 7/32" socket worked best on my 2008 model, the 6mm worked best on the 2003 Vibe at the junkyard.

OFTEN TIMES IT IS A BAD BLOWER MOTOR THAT CAUSES THE RESISTOR TO FAIL IN THE FIRST PLACE. Bearing friction gets worse and worse in a bad blower, causing the motor to draw more and more current. Increased current burns out the blower motor plug and resistor, as well as causes the motor to smoke. The resistor will overheat, but likely not blow a fuse. When removing the blower try spinning the blades to check for friction.

Therefore it might be a good idea to replace the blower motor and the resistor at the same time, or else, as stated above, you'll keep blowing resistors; a bad blower motor might be the root of the problem in other words.
