Replying to: barnowl3 (Nov 05, 2008 4:13 am) thanks for replying, no the windows do not strain going up, do you think this is a major issue something that could possibly be a huge problem till i get it in, or is it just something minor?

Replying to: marcb2 (Nov 04, 2008 5:08 pm) 2004 silverado, left turn signal on(only left)and hazards flashed. Hear its a common problem, well I did some research online and it turned out to be an easy fix. All I did was replaced the flasher behind the fuse box and it solved the problem. Was surprised how much the flasher costs though, it was $94 at dealer but you can get it at gmpartsdirect.com for $52. New flasher also has different Delco Part # then stock # and sounds much stronger when flashing. Saving receipt cause i see a recall in the future.

#259 of 356 CK1500 Body Control Module by fastestbbc Dec 01, 2008 (8:02 am)
I am having trouble with a 99k1500 that is starting and stalling. I believe it is the Passloc system, so I have went in and put a resistor in in place of the key. Key measured 2350 ohm I used a resistor pack of 2357ohm. However I am still having the same intermittent problem. I will do the 10 minute key on relearn this evening, again. If it still persists what are the thoughts for a bad BCM? And can I just get a used one and pop it in or does it need to run a relearn of some sort? What is the preceedure? thanks for the help

#261 of 356 04 Sierra Steering Wheel Controls by sporty06 Dec 22, 2008 (6:31 am)
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 356 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
