#371 of 396 4wd not shifting on the fly
Apr 30, 2012 (9:34 am)
My 03 Silverado has ceased to shift on the fly. I've got the manual shifter on the floor and it just wont budge from 2wd to 4hi until I'm basically at a complete stop. It used to shift on the fly smoothly so I'm not sure what's going on...maybe a sensor or something? Any thoughts on where to start before I give in and take it to a shop?

#373 of 396 Static in radio from bug guard
Aug 04, 2012 (1:26 pm)
does anyone else have a problem with static in the sound system due to the bug guard? Even when I turn the radio off, the static still comes through the speakers. If I remove the bug guard, the static goes away. Put the guard back on and the static returns. All of my friends with chevy trucks do not have this problem. I'm lost at why mine does it. HELP!!!!! Thanks in advance.... PS, This only happens when driving down the road. If I stop, it goes away, start driving again and it starts w/ static again. remove the bug guard and the static never comes back?????
#374 of 396 1980s Chevy 1500 4x4 Short Bed
Aug 27, 2012 (4:41 pm)
Where can I find a website or list, chart etc. of 4x4 curb weights ? I want to build a 4x4 for mud racing, starting w/ the most light weight 1/2 ton 4x4 out there (full size).
I heard the 1986 Chevy 1500 short bed was the lightest, but,,,can't verify this via LOTS of Google searches.
Can anyone point me to where to find "vintage" truck curb weights ?

I have a '98 Dodge 2500. There is a "4x4 lamp" actuator on the passenger's side axle housing..this can and did cause the 4x4 to NOT engage. Then there is the actual actuator, vacuum operated, on the axle housing round with two hoses coming off it (again, on my DODGE) then there is the actuator on top of the transfer case that is also vacuum operated.
The vacuum lines must be put back CORRECTLY for the 4x4 to work !! There were 4 vacuum lines on my Dodge with the 241 New Process transfer case (same actuator as on the 231 t. case)
Check the vacuum lines for cracks, splits, holes, wear etc. and as you said, the fuses. Check all these. The electrical actuators, on axle and transfer case, were both around $15 ea. so I replaced both. Check all these again and see what happens.

Iím no expert by any means; I can just tell you what I did to get my FWD running again. I have a 2000 Chevy Silverado, Extended Cab, and Long Bed with 180,000 miles. I bought the truck about one an a half years ago or so, and the FWD didnít work back then. So, last summer I started working on it. I did just as you have done, and looked it up on the internet. I went to a number of different sights hopping I could find a quick fix and save a lot of money. After reading I found things I could do with the help of youtube videos. I did the following:
1. Looked for a blown fuse. I only found one fuse that said FWD, and it was the one on the inside of the cab. Looked good. So that wasnít it.
2. Changed the selector switch. You know the push button thing, in the cab. This wasnít it either.
3. Changed the actuator. Nope not it.
By this time I was not too happy; therefore, I did the unthinkable, I took it to the Chevy Dealer. After all having a FWD truck, but the FWD doesnít work, just donít seem right. Kinda got my feelings hurt when they said ď$100.00 dollars an hour.Ē No thanks. So, I did without the FWD last winter. Luckily, it wasnít a bad winter.
So, before this winter, I was bound and determined to get it working come hell or high water the things gona work. After replacing all the parts last year and it still didnít work, I knew it had to be electrical.
I found a web site that has all the electrical information for my truck or any vehicle for that matter. Itís called alldata.com. Granted, I did have to pay like $25.00 for a year, but I did it anyway. And, low an behold, there is a fuse. Itís not labeled FWD, its labeled ATC. (Automatic Transfer Case) Itís under the hood with all the other fuses. So, I donít know what the actual problem was or how the fuse got blown, all I know is after doing all the steps above and replacing this fuse, itís working. I just had to try them all, I guess. Good Luck!!! And thanks everyone that posted on here. IT WORKED. I donít know which one done it, and donít care. I got my FWD back.
