easy to pull the motor. Pull the trim below the glove box and whammo, there it is..

What is it doing?

 

The dash switch goes out more than the blower motor on a DI.

 

Well, Here's the deal. My truck nearly burned up the other day. I had a eletrical short occur on the blower circuit when it was turned on. I was able to remove the motor. To my suprise the motor is seized. I replaced the motor but now the switch will not turn it on. I have confirmed that there is power coming from the switch to the motor. I also confirm the replacement motor works. My question is the resistor pack for the switch, can it go bad? The switch itself seems to light up the test light that I am using. Any ideas would be great. Thanks.

 

yes the resistor can fail also--the switch fails ussually in way that the blower just stops blowing but tap the switch and it will start again---your problem does not blow on any speed???if so i say resistor
