2001 Chevy 2500HD Fog light lens fell off somewhere

Explode ? No. Fail ? yes.
Cover the broken area with shipping tape and order a new lens from the dealer.

Hi Lois,here's a video to replace your fog light, Fog Light Replacement 2000 2005 Dodge Neon 2001 Dodge Neon 2 0L 4 Cyl

There was a tsb on this issue affecting your vehicle as well as suburbans. Their recommendation was to replace the bulb socket.

i would say you have two options, purchase a new fog lamp(s), or you could use JB weld epoxy for plastic(you can find in any auto store) and once it fully cures there is virtually no chance of you ever taking the lens off(if you should ever need to , but i doubt it). just take fine grit sand paper to rough up the application area a bit, then mix epoxy and apply.

2001 chevy silverado 2500hd battery light flashes intermittently. no problem with battery or alterntor. both tested ok. no problems with starting or running. voltage gauge reads just above 14. no problems with anything except battery light flashes. what could be the problem?

check the ground on the lights.

You change it from the front of the car.

To remove the fog light - firmly grasp the black plastic lens protector along the outer edges and twist it to the left (counter-clockwise) to remove it.
Now remove the two bolts just above the fog light - the whole thing comes out as an assembly. Then you can disconnect the socket from the back of the assembly

I have a simular problem. Only mine does not some on. I tried to replace the turn signal switch assembly with a used one. The replacement work ok on the fog lights but the rest was bad. As near as I can figure it, the switch assemble is not well made and had many ways to go bad. Either replace the whole assemble or wire in a bipass switch. I am going to go with a bipass switch. I don't trust the new jeep products.

I had the same problem, lens can not be re-insered, you have to buy a whole new assembly. About $125.00 each, they changed the adhesive on the replacement lens.

If the problem is that the brake lights will not turn off, the problem is most likely the CHMSL relay. An easy check is to take the cover off the fuse block mounted on the driver's side fender well and swap the fog lamp relay with the CHMSL relay. If that fixes it, just get a new relay for the fog lamps and you're good to go. Note, my 2002 s10 does not have fog lamps, but it still had the relay populated in the fuse block.
