Having heater problems with a 2004 dakota 4x4 3.7L, heater fan quit won't come on at all.Also looking for a repair manual for the same truck.

 

first off look for the ppower wire. tap into an aux. feed and see if it works, if not its the fan, if it does than you blew a fuse or a fuseable link. switch might have shortened out also. check yo see if the cig, lighter works. i believe they are on the same fuse

 

Superdak has you on the right track. Also, you can download the manual the lil posted a while back.

 

Thanks
