    2008 Tahoe New to me but have some issues

    I will check this stuff off. I looked at the chassis and everything is astonishingly clean. It was originally from Texas and spent some time in south Florida. It looks like it baked in the sun, but the paint is in great shape. I have found some of the plastics are all deteriorating. I am one for...

    2008 Tahoe New to me but have some issues

    I don't have any idiot lights on the dash. I had the SES pop up when the pressure sensor crapped out on Christmas. When you say sender are you referring to the oil bypass valve on the oil pan? If so I am planning to pull the pan and block it. While I am doing that I will change out the pickup...

    2008 Tahoe New to me but have some issues

    I purchased a 2008 tahoe Flex fuel thinking it was a good deal but already want my 03 fixed. I wanted to ask if there is anything I need to watch out for as I repair what is wrong. I bought it with 89000 on the odometer, but I have had problems since I got it home. So far I have disabled the...

    2008 Tahoe Service Charging System

    I have HPTuners so tuning won't be an issue if I have to go that far. I did hook up my OBDII scanner to verify the vin and make sure there were no hidden codes, and everything is clear. From what I can tell the battery is new. I have not verified the manufacture date, but its a duralast gold...

    2008 Tahoe Service Charging System

    I appreciate the feed back. I have read information on it, but its hard to not be skeptical. My 03 is down waiting for me to get the new motor built, and I had to find something to drive. Its hard going from older to newer because of the changes in the system. I am picking up on everything that...

    2008 Tahoe Service Charging System

    Just bought an 08 Tahoe 90k on the odometer. It has the flex fuel 5.3, 4L60e, 2wd, and has the LS trim package. I have had problems with the Charging System since I got it home. I took the Alternator and Battery to have them tested and they both passed so I reinstalled them. The Service Charging...

    Rear brake over use.

    My 03 Tahoe has 2 piston calipers on all 4 corners. For some reason my rear brakes always wear quicker than the front. Is there an issue I need to look into or a way to balance the system? I have checked the calipers and bled the system, but have always gone through 2 sets of rear pads to 1 set...

    Cruise just went out and no bad fuses.

    I like to randomly use the 4wd to give it some use. This past weekend I used it and it didn’t engage 4 Low. It stayed in 4Hi but the 4 low light was on. Didn’t think much about it but noticed on the way home that my cruise is out now. I have checked the 4wd again and it seems fine now, but...

    Aftermarket dual climate control issue.

    I have no issues with anything else. All of the grounds are still intact and harness is still in great condition. The original unit worked fine until I tried replacing the lights and the temp controls were damaged trying to remove the plastic caps. That is why I have this Dorman piece. If I have...

    Aftermarket dual climate control issue.

    All of the functions work but it is just temporary. The controls have worked for a few weeks to only a few day after going through the setup again.

    Aftermarket dual climate control issue.

    I have an 03 Tahoe that I replaced the main control with a Dorman unit due to damage to the factory piece. After installing you have to program the controller, and the system won’t stay programmed. Does anyone know what to do to correct this issue? I have disconnected the battery, removed and...

    Reduced engine power without cel

    I had to throw money at mine to figure it out. Everything I researched said it was the TCM. I started with that and it lasted a week. Then it started kicking codes more frequently. So I replaced the TPS. Then it went crazy and I had to leave my scanner hooked up to delete the code to get home...

    Reduced engine power without cel

    I just had the same problem with my 03 Tahoe. I replaced the TCM and the TPS and neither fixed the problem completely. I had to replace the throttle body. The drive motor for the throttle body was going bad causing the throttle blade to flutter at idle which caused rough idle and reduced engine...
