Cadillac Repair: 1983 Cadillac Blower Motor, heater blower, blower motor

Question
My '83 has 42k miles.  The blower motor has stopped working recently.  At first, it would come on and than shut off after 30 seconds.  Now, the does not come on at all.  The A/C is working and the vent opens and closes, but there is no Blower Motor.  Is there a relay I can change out?

Hello,

Very common problem. They use a resistor module under the hood at the right side by the blower. If you can find the part, its about $250.00 plus labor. Cadillac has had heater blower problems for 30 years and you type of car was notorious for it.

I used to see a switch under the dash of one of these that wired to the blower would give you at least high speed.

These resistor modules were common to fail drawing the battery down as well.
