Can the backlights for the steering wheel controls be changed? I have had almost all of mine go out one by one over the past month. It seems like each switch should have its own bulb but I can't figure out if you can replace them or not.

#263 of 358 electric spark control module code comes up by mdavid Dec 22, 2008 (9:32 pm)
i bought a '95 gmc sierra 2500 that needed a new engine. when i bought it, the engine light came on. my mechanic friend changed teh engine with a 2000 rebuilt engine. its a 5L 305, however, after changing the engine and swapping some parts around the engine light is still on. he states teh engine runs great and he looked for codes and the code for the electronic spark control module came up. he looked for the module and says he found it integrated with teh computer, however, he says the truck is a '95, but the wiring harness is factory installed and for the yrs 96 - 2000.   does anyone know how to get my engine light to quit flashing when only that one code comes up for the module or what the problem is??? and if i, as he is suggesting it may be the computer, what yr/truck do i get teh computer from???   he says he checked the vin with chev and with his code reader and both say its a 95 but he can't figure out why it has a ;96 - 2000 wiring harness.   any replies would be appreciated and can be emailed to me if possible to, snooky71hotmail.com   thanks   mike d

#267 of 358 04' Silverado 2500HD 6.6 Litre Diesel by cor3720 Jan 02, 2009 (4:10 pm)
Upon start up, engine would run very rough, excessive noise, no power or rise in RPM's upon pressing gas pedal. Checked oil and it was low so I replaced it as I heard there was a sensor that wouldn't allow engine to run normally. This didn't help. The weird thing is if I start the truck, turn it off, drive at idle 3-4 times, off, on, off on, you get the picture. It will run fine for the rest of the day. Then the next mornig, I do the process all over again. Fuel filter was replaced about 10k miles ago. I have opened the wing nut on the bottom of the fuel filter in case there was water in the fuel. Any help would be helpful as money is super tight right now. The check engine light is on when it runs bad, then it will go off when it is running good. Thanks
#268 of 358 CodeP1516 by patsyms Jan 05, 2009 (11:45 am)
Last week I had the throttle body replaced. Brought it home and parked it until today. My 2003 silverado is doing the same thing it did before I replaced the part. Do I need to drive it more, or something to "reset codes"?
#269 of 358 Outside mirrors remote adjustment stopped working...... by lromjue Jan 05, 2009 (1:35 pm)
I have a 2001 GMC,Sierra, 95K. Recently outside mirror adjustment control stopped working. In past, controller has on a very few occasions not worked or at least was intermittent, but always finally did work. Yesterday found that it was completely dead. No response at all.   I will check fuse. Where will the fuse be located?   If fuse is not the problem what else should I look at?   Thanks.......................larry
