Thank you for the add....
I just bought a 1999 Dodge Ram 1500 Sport. The blower motor will not work in the truck. I have tried another blower motor that works in another dodge truck but not in mine. Then I switch, tried my motor in the other dodge and it worked in the second truck. I also have changed control unit and resister but still no air flow. I can hear the compressor trying to cycle. Any advise?


Thank you in advance

 

Gonna move this to the Second Gen Tech section for ya.

The control head provides ground path for the blower motor. Are you actually getting power TO the blower motor?

 

my fix ended up being, replacing ignition switch. The switch fixed the blower motor issue and my windows not working issue.
Thank you
