#36 of 458 2001 chevy tahoe electrical problem
Apr 07, 2008 (8:29 pm)
Any ideas? I attempted to start my tahoe this afternoon. It barely turned the engine a smidge and then clicked a few times. I heard the vehicle speakers clicking, quickly turned off the radio, and it continued to click for a minute or so. Tried to start vehicle and got absolutely no power. With a jump, go it to start, pushed on break and put in reverse and it died before it started moving. Couldn't get a good start after that. I few hours later, came back with high quality(4gage) cables, started it, backed it out and drove it home (3 miles). I tried to reproduce problem with loading electrical (AC/ back window defroster, lights, etc.. It continued to work, but periodically the RPMs would drop by half and lights would dim. Then, suddendly died and absolutely no power. (battery is new and tests good.) It is as if a master switch of some sort was shut off. If I provide an external jump, I believe it will start or get power in the vehicle again...ran out of daylight. Any ideas would be appreciated.

The symptoms sound like either a bad battery, loose/corroded terminals or wires connectors to the battery, a bad alternator which isn't charging the battery up, or something is defective and is draining the battery down while it sits.

I have a 1999 Chevy Tahoe Z71. I recently replaced the 5.7 with a GM Performance HT383E engine. The engine is touted to have 322 HP and over 430 lb ft of torque when mated with OEM injection, exhaust intake, parts. While the engine is stronger, it is not representative of the claimed increases. I had already fitted the 5.7 with edlbrock headers, a flowmaster cat back system, an AEM Brutforce Intake, and a SUPERCHIPS power programmer. These additions made significant and noticeable gains on the OEM engine with 160K miles. When I put the new engine in, I was able to mate all those bolt-ons in the swap. However, it doesn't produce the neck snap one would expect with almost 100 more HP and 100 more lb ft of torque from factory specs. It just seems to be starving. It sounds really mean and has a noticeable lope with the stroker configuration, and it is a little more peppy, but opting for a $5k upgrade instead of a $2k upgrade is simply not being realized. I'm wondering if I need a high-output igntion system to aid in the burning of the fuel. I've noticed that the residue leaving the tailpipe is leaving a good bit of soot, indicating unburned gas escaping.
Now...onto other new issues...the truck idles with a slight surge, sometimes elevating to a rise in RPMs, countered by a reduction that almost mimicks dieseling. In addition, my wipers only work randomly and start and stop on their own. My AC blower is also not working all the time. Sometimes all the settings work and sometimes only some of the settings work, and sometimes none at all. Also...my previous engine lost oil pressure and the gauge moved a bit back and forth for a few minutes. When the truck was returned to me after the swap , the oil pressure gauge was stuck on a wide open (far beyond the highest pressure reading) position. It does not fluctuate or bounce at all regardless of engine speed.
So...that's about it... I love my truck. I was eagerly anticipating the performance beast I put under the hood. It seems I didn't get much of a bang for my buck and I now have "gremlins or ghosts in the electrical system". Any ideas?
#40 of 458 2003 Tahoe Headlights
Oct 23, 2008 (4:26 pm)
I have a 2003 Tahoe and I am unable to turn off the headlights at night when the vehicle is parked. I have had people tell me to hit the dome over-ride button three times in a row and it will shut them off, however it does not. Someone also told me to set the emergency brake. I have done that as well and it still does not turn them off at night. I called the local dealer and they do not have any other information. Does anyone have any other suggestions?

Well not sure how you are keeping your battery from going dead, until you figure out the cause of this problem. Consider pulling the fuses for the lights, or the relays. Be sure to put them back before needing to drive at night.

Sorry I just realized that it seems as though the lights are staying on when the ignition is turned off, but that is not the case. What I am asking is how do I shut the headlights off at night while the vehicle is still running and it is in park

In our 97 Burb, that was done by putting the parking brake on. In our 07, you turn the headlight switch from "auto", counterclockwise to the "O" position.
I think your 03 is more like the 07, but I believe it's written up in the owners manual one way or the other.
