Couple issues with new purchase

[DieselDummy]

04.5 SLT Sierra

I have no power to driverside door, changed out whole switch, still nothing. Any ideas on where to start looking?

Second issue is no fan motor, is there a resistor for those? Motor is new, works if hotwired, but obviously no control of it that way. Any help would be great. Thx

Check the wiring in the door where it pivots, sometimes wires can flex a little too much and over time break wires. I've fixed a few vehicles that had this happen.

For the blower motor there is a relay and the wiring to it is notorious for shorting out and burning up, you're just going to have to get under there and check the wiring and the resistor. Sometimes the resistors burn up too.

Copy that kinda figured

Yeah your plugin for your blower motor resistor is prob fried. They sell pigtails at the dealer and I think my local Oreillys has them too. I'm assuming you've already checked ALL fuses, both in the dash and under the hood.

Yeah, checked all the easy stuff

Ok, did little checking on window issue, have power to door switch, changed out switch, still nothing, all wiring into door looks to be in good shape? Kinda stumped!!!#

 

[Huffy67]

Have you tested for power at the window motor when you hit the switch? The motor may just be bad.

No, but none of the windows work or the door locks nor heated seats

bcm?

 

[DieselDummy]

What and where is the bcm?

 

[DieselDummy]

Assuming it's body control module?

 

[DieselDummy]

Changed bcm, still nothing, changed door harness, changed fuse block, still nothing, anybody got a bright suggestion?

Do the windows work from their door's individual switches? If so, it could be a bad drivers door module. As for blower, the relay setup/plug/harness is usually the issue

 

[DieselDummy]

Had 3 different driver switch 's didn't work, but no windows or door locks work at any spot.

 

[DieselDummy]

Anybody have any ideas, I wanna burn it!!!

 

[DieselDummy]

Bump, anybody got a clue?

 

[clrussell]

Have you flashed all these modules you've installed in the truck? Some are vin specific and won't work without flash I think.

Did emergency relearn for bcm, but that's it, gonna grab a tech 2 this weekend

Anybody know if the module for heated seats has anything to do with the windows?
