Hello Durango parents, girlfriends, boy friends, my Durango is my girl, I love how she has treated me, Well Ive treated her...
my problem arose after i did the heater core on the ol girl, she required quite a bit of labor intensive time and required quite a bit of undressing,
i labeled everything that i took off, and thought I got her put back together right,
but, my second test drive, was a weird ride and has been ever since,

I pulled up to the stop light noticed my engine light on, and at the same time my blower motor kind of dimmed out!!!! and there was this faint kind of dying buzzing sound in the dash, and another click sound,

this thing has baffled me for several months now, because it doesn't do this all the time, and once in a while when I click my power locks, my temperature control lights come on even when the vehicle is parked and not running, I can go click the lock switch and get just the temperature control lights to turn on, and then if I turn the dimmer switch to off position the temperature lights go off.

I know this sounds crazy, but help me take back my girl!!!
Ive changed, temperature control switch, rear defroster switch, rear power lock actuator, driver door actuator.
blower motor is next, but when Its working it works great..

 

Make sure you got the lower left and right bolts tight to the body. The ones that hold the dash bracket to the sides right by the door openings. Those brackets/bolts are the return path back to battery ground for your dash grounds.

 

thanks, that gives me a starting point for sure.
