Ok let me start of by saying I am a heavy equipment tech and pretty good with electrical issues/problems but I ran into this one and I wanted some of your more experienced guys to help me troubleshoot it. I am working on a gmc sierra, 2000, v8. The keyless entry/remote start unit is a viper one. She had a blown passenger marker light, underneath her headlight. Simple fix new bulb, but while I had that lense removed I noticed that the inner most bulb was blown and had some charring around the socket area but no burnt wiring. So I just stuck new bulbs in and proceeded to test the lights. At that time I noticed that when you hit the lock/unlock on the remote that no lights flash on the vehicle with the exception of the interior dome light. Now I asked the owner if it flashed prior to having brought it to me and they said that they used to flash front and rear with the lock/unlock on the remote. I started to think fuse somewhere so I checked all the fuses in the engine bay and in the vehicle. None are blown from what I can see. So what I need to know is what these lights are used for and if there is a relay or fuse that controls power to them so I can continue to test things and find the source of the problem.

 

aftermarket alarms are some real ****...all we'll do is disconnect em and throw em in the trash

 

I don't have that option unfortunately, but I think I may know where to look after talking to a few friends about it.

 

ok found the issue it was a loose fuse for the remote setup white wire 10 amp fuse it was not pushed in enough to make proper contact.
