GMC utes seem to be a REAL problem should have bought a Ford or Dodge. Do not belive the OLD story--- If you can not afford a Ford dodge a Dodge

I am assuming you have a manual transmission. First I would check to see if it came with the dual flywheel. If it did then this is the problem. If it didn't then the pressure plate is weak or the clutch is worn out. If it is an automatic, there are several things that would cause this. Torque converter. solenoids, clutch bands, clutch .....

I need a belt routing diagram for an o 06 Duramax with air ps etc

please use complete sentences to describe issue more accurateley.

Yes you would need to put in a fuse. It is in the fuse box under the hood at the driver side. it may be labled as LT or RT TRLR ST TRN.

check the relay fuse under the hood

CHECK THE WIRING TO SEE WHICH WIRES NEED TO BE REPLACE

You have replaced the resistor and the blowwer is good and the fuses are good then i would say its in the switch or power to the switch, maybe at the ignition switch there a bad wire . sometimes the power wire going from ignition switch heats up and causes a bad connection, if you pull connector off the switch make sure the connector to ignition switch is not melted or burnt and also check blower control for the same, i would say that your blower is bad and drawing to much current if you have replaced a few resistors, i think maybe theres a fuse under the hood in the fuse /relay box that may be out or the connection at the switch or ignition is melted. hope this helps.

Was it running OK before you changed the fuel filter?

Double check all grounds make sure that they are hooked up and free of rust

Check fuses.

not too bad of a job, pull the fan and dampner. ive heard of guys saying they can do it without pulling the dampner (i dont know how?) it doesnt take long to get it off. dont put a cheap w/p back in, if the shaft seal goes out you will have alot of coolant in the oil.

Hello. Remove the screws near the door handle. Use a putty knife to gently slide between the panel and the metal frame and pry the panel loose from a series of clips. If u break a clip don't worry as every auto parts store carried em. J.

Sounds like tank sender unit resistor damaged or broken

Suspect 7 pin connector problem , you should have power on the 8pm positioned and the centre pin position as you look into the socket (on vehicle. These pins are both male pins as you look at them . If ok check trailer wiring where it splits for either lamp assy ! Good luck
