#314 of 318 light issues by cbowles Oct 13, 2009 (6:31 pm)
I have an annoying light problem, having trouble fixing! My license plate lights weren't working so i decided to change the sockets and bulbs, apparently big mistake. Now my drive lights in the front and rear are not working along with my dash lights and passenger side courtesy light. But my break/signal/reverse/head lights are all working perfectly. Im thinking this may be a ground issue..... need help!   Replies to this message: sean1999 (Oct 14, 2009 10:43 am) the_big_al (Oct 15, 2009 9:51 am)

Replying to: cbowles (Oct 13, 2009 6:31 pm) I am having to guess here but if you have a trailer wire harness attached, it may have rubbed and grounded itself out. Ground issues on the S series seem to be an issue and with a bazillion grounds it is tough to trace which is the culprit. Also I have heard that putting bulbs in that are not the exact appropriate bulbs will jack up the system as well. I love my S10 but the problems are frustrating. Its a truck. It should be simple. Good luck and let us know what you find.

Replying to: cbowles (Oct 13, 2009 6:31 pm) I also point to a ground issue... I just fixed one on my truck involving the turn signals in the rear. Might try and see if you can locate an electrical schematic to see what is tied into what (that may or may not help since a lot of things are tied into one thing or another depending on what is being used or not used), or just start tracing wires. I would start at the license plate lights since that is where the problem started and go from there. Trace all the wires connected to them and see if there is a wire rubbed bare or corroded.
#317 of 318 Problem after changing headlight. by esw03 Nov 24, 2009 (3:21 am)
I have a 1997 S10 ZR2. Last night I changed one of the headlights while the truck was running, so the daytime running lights were on. After changing the headlight, the power windows, cruise, heater mixing whatever (?) won't work, and the ABS light is on all of the time. I have checked all of the fuses and breakers and they are all ok. Does anyone have any ideas on what could be wrong. Thank you in advance. Replies to this message: gonogo (Nov 24, 2009 8:14 am)

Replying to: esw03 (Nov 24, 2009 3:21 am) Try removing the negative battery terminal for 10 minutes, maybe a processor will reset.
