Does anyone know of a way to upgrade or convert the computer in a 01 Silverado so that half of the injectors are not used while on the highway.

That is a nightmare. Reminds me of a friend who rewired the factory harness when installing an aftermarket stereo rather than buy a $10 adapter at Best Buy. Blew a few fuses then the headunit itself.
 
Personally, I'd check the power connections first. That is where the guy is getting the power for the lights, etc and go from there. Could be he has a few of them crossed or all connected to the same place. Watch for splices as the factory doesn't do that only diy installers.

Hi-
 
Did you get any aftermarket add-ons or did you get another alarm to supplement the factory? If you did, most of them don't work well with GM vehicles. I went and had a Viper put in instead of the Factory. Much better protection.

I have an 02 1500 HD. the running light on the left side is out. I can replace one for $27 with the amber turn signal lens or the pair with clear turn signal lens cover for $67. Any opinions on this?

You're talking about replacing the lens? or lens and bulb?

Just a simple thought, ... check the ground connections on the back end of the truck. I noticed that the bumper had been replaced. Quick and easy, and it could explain the ramdom lights.

Low washer fluid light always turns on in 2002 Chevy Silverado by kazontite

Whenever I turn my 2002 Chevy Silverado Z71 truck on, the 'Low Washer Fluid' light turns on. After it's on for awhile it then shuts off. How would I go about in fixing this problem?
