| 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"? | |

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 |

I have a vintage 1993 Chevy Blazer K1500 that still runs like a sewing machine after 235K miles. But today, the temp gage went tit$ up. That is, it reads off the high side of the gage even with the engine is stone cold, ignition switch on or off. The computer has stored a code "15". I followed the Haynes manual recommendation to remove the glovebox and wiggle the connectors to the computer, no change. I unplugged the engine coolant sensor connector, no change. Do I have an open or a short? I hate electrical issues. I was planning on replacing the sensor, which may happen tomorrow, but I fear the problem resides somewhere behind the instrument cluster. has anyone in the Silverado forum encountered a bad gage problem like this one?

| Hi, Checking to see if anyone has heard of a fix, bulletin, idea about my problem. The 2 WD ext cab PU has the 4.8 V8 auto and 175000 miles. During very cold weather, below 28deg F, the charging system has intermittent temporary failures which look like momentary dips on the charging meter and looks to oncoming traffic as if I am flashing my headlights. The failures are never more than a few seconds at a time. I have checked for loose wiring, have replaced the battery and alternator. Still have the problem. Is there a particular component I should check that might be exposed to the elements and not quite work when cold? I have been unable to find a similar problem on this forum, except the ignition switch guy, and I don't think this is the problem. | |

2002 Chevrolet Silverado 1500 4x4 Z71 5.3 Vortec Engine. 109000 miles. Only on cold mornings/days does it stall and idle really rough and missfire. Here is the strange part: if I unplug the MAF sensor, it runs fine. If I plug it back in, goes right back to crap. So I thought i had found my problem and replaced the MAF Sensor but to my surprise it did the same exact thing. It is throwing a coolant temp sensor code so maybe that is the culprit. My question is if it is a bad coolant temp sensor, why does it run fine when I unhook the MAF? I also tried unplugging the coolant temp sensor but it still does the same thing if the MAF is plugged up. |
