I looked all over the forum for an answer but cant find one.My heater just quit working.I replaced the heater control resistor and that did nothing.Took the blower motor out and hard wired it to test it and it's working fine.Checked the clip to the blower motor for power and it's got power.Put it all back together and it worked fine for about 10 seconds then came to a stop again.Not sure what I should check next so any advice would be much appreciated.Thank you for your time.Oh ya, My truck is an 07 3500 6.7 Cummins.

is there still power to the plug when the blower motor shut down? I've seen it before that on the bench they work fine but when you put them back in the vehicle with the resistance they overheat and quit.
