It felt like my 4 wheel drive wasn't working... I put the truck on jackstands... started it put in 2H drive... L/R tire spun... When I held it from spinning then the R/R started to spin... I put it into 4H & the F/L tire spun... (but not as fast as the rear tire...) I held the F/L from spinning then the F/R started to spin... But again not that fast... I was able to hold both tires from spinning while in 4H... I was at a loss. So I took it off the stands to pull it up to my garage... I put it into 2H then drive... let go of the brake & gave it gas to move the vehical forward & the RPM'S went up but the truck rolls backwards!!! I stepped on the brake again... went to put it in PARK and the transmission started making a clicking noise... so I moved it back to DRIVE & 4H... Still no tires moved... Left it in drive, shut engine off, moved it into PARK but when I let go of the brake it started to roll backwards like it was in nutural even though the dashboard switch says its in 2H...Its like my transfer case is stuck in nutural even though I hear the transfer case motor moving...

my 4 wheel drive light blinking wont switch to 2 whenn drive stuck in 4 high

I replaced both front hub assembly's/sensors and still have the problem with my abs at low speeds prior to a full stop.

Is the valve sensing vacuum or pressure when it runs? Does the ECM turn the purge on or does the purge just notify the ECM when it is running? Any idea where to look first in troubleshooting the purge system?

How do I check the HVAC control module codes

Started having problems with my heater last winter. It would not switch from ac to hear unless I turned my truck off. Well this year I've got no heater at all. It's not the control switch like I thought it might have been, already tried it. Do you have any suggestions?

When you push end of shift lever to engage towing the towing on transmission does not engage. Truck equiped with tilt steering.

My truck seems to lock all 4 wheel at once. Replaced the master cylinder. Had the wheel speed sensors removed and cleaned. Calibers pads and rotors checked, no problems there. Truck will roll only about 25 feet ONLY after removing all fluid. Once replacing fluid and bleeding, ALL wheels lock; LOCK, will not turn none.
