SOURCE: Will not shift into 4wd low but will shift into 4wd high

Thanks for your response johnnyc85.... I did some searching on the internet and found it. When you need to go into 4wd low, just turn your knob to the 4wd low position and when it starts to blink just put the truck into drive or reverse and move about 1mph it will lock right it. It takes about 5 seconds to engage.

SOURCE: where can i find 1 of the top screws to the throttle body forchev

A Chevy dealership should have any bolt you need.
I payed around $2.50 for a wheel bearing bolt for my '97 Grand Prix.

Hello streets54, my name is JShreader. Thank you for choosing fixya.com.

First, you have to remove the Upper Radiator Grille. Behind the Headlamp at the top of the Front Bumper, access the lower inside hidden Headlamp Bolt. Only loosen the Bolt. DO NOT REMOVE. Now remove the 2 Headlamp Screws, then the Hidden Screw...now the Headlamp Housing should come out. I uploaded the procedure in .pdf format. You can download it by clicking HERE. I hope this helps you. If you have any more questions or need any more diagrams, please don't hesisitate to ask...Thanks again, JShreader!

I have a 2007 Chev Silverado 2500HD. When I put it in 4wd it makes a lugging feeling and shakes. I cant get it out of 4wd unless I hit a pot hole or stop completly. What could be wrong?


How fast are you going in 4 wd? In 4 high 50 mph is plenty fast and 4 low is not a good idea unless you need lots of power at a low speed. It may be "lugging" due to the fact that it does require a good deal of power to operate a second differential - I not sure what your experience is with 4WDs. In my experience I have had to, at times go as far as reversing the vehicle to fully disengage the 4wd after a day on the 4wd trails.

Unfortunately You need to read the codes for the Transfer Case Control Module. The Diagnostic codes will help you in the direction to repairing this problem. The switch light goes out when there is a problem and the Transfer case switch is disabled.

Thank You,
