2003 Chevrolet Tahoe: headlights failing or too dim

Filed Aug 30, 2022 · Acceleration, Electrical · AZ

I bought my 2003 Chevy Tahoe used and as is at a dealership for $10,000. Yes, I've been robbed. The truck is in great LOOKING condition. Has a little bit of superficial dings and a couple dents but overall exterior is great. Interior isn't shabby. Has wear on the driver's seat but not bad. The first thing that happened, I was on my way to work at 4 in the morning, turned on right blinker to change lanes, about blinded the guy in front of me with high beam lights. I thought I had bumped the switch, I took the right to get off at my exit I was more mindful. Definitely not a me thing. The high beam came on with the right blinker. So, the next thing. CD player runs continuously without a disc in. I cannot put a disc in. There may be discs already in there, it is a 6 disc changer, but it will not play. The radio has a mind of its own. Plays what it wants at anytime its on. My husband drove it, tried to adjust the driver's seat and all it did was growl at him. It doesn't move except forward and back. My speedometer had a glitch one time. I was driving at 35mph and it showed 60mph. I turned it off, then back on, hasn't done that again. My heater works but it's difficult to change the individual temp settings. Almost as if the push buttons are worn inside or have a bad connection. The air conditioner only works when I'm on the freeway and not in stop and go traffic. The first time I turned on the AC, it blew all hot air for longer than 10 minutes. Halfway home I turned it on again but kept the button in off setting, I have cold air. There is a loud popping underneath when I turn left. Also, dropped into 4H driving down the highway at 65mph. Thought I was going to die. I have to drive in auto all wheel because the buttons are messed up. In 2H or 4H I get 4L. It is a mess. The dash is confused. 4 wheel does not go in easily, It bangs when it goes in and comes out. It really isn't safe but I was soaked on the price, I am female and first purchase. Should have bought a Ford

When starting the vehicle, check engine light comes on and dash says reduced engine power. Vehicle will only drive about 15 miles per hour. Upon researching this through various internet websites, this same problem has and is happening to a huge amount of 2003 tahoe owner's and it's always a faulty wiring harness problem - yet gm refuses to acknowledge there is a problem. On a side note, headlights have always been very dim.

High beam indicator lamp is too bright. Difficult to see past it to view the road ahead.
