At the base of the brake pedal you will see the brake light switch. See sources and related links below for more information. I can not manually flick the lights as fast as they flicker when I am driving down the road. I have a 05 Trailblazer and had both of these problems. These problems only started after the alternator was replaced.
I contacted a local dealer who said there was no recall for this model and it would cost me over 500 dollars to repair. If the oil light is shining check the engine oil this could be a sign of low oil pressure. I was told by the dealership that my entire dash cluster needs to be replaced in order to have working oil gauge. Example fuel gauge way past full, oil pressure gauge reading 0, charge gauge maxed out tachometer completely off the scale and speedometer inoperable. We notice it when driving to work in the pre-dawn hours and it occurs most frequently when we let off the gas to slow down. We took the vehicle to our local Chev dealer and they could find no problem and offered no support.
Sun roof leaked profusely, had it fixed. I am unable to drive my vehicle at night, it has been to a certified Chevrolet dealership twice now, they have stated that everything is running correctly and that they cannot find anything wrong with the vehicle. Sending unit has gone bad again. Instrument clusters such not be failing at such a horrendous rate. I have read where others had the problem and it was thought to be some kind of defective connector or similar on part of the wiring harness that plugs into the alternator. It turned out to be the secondary air pump either clogged, not running or something electrical with it. This is an expensive repair about 5-600 dollars.
Fuel gauge currently not working properly, unreliable. I took the vehicle to the dealer and they determined it was a fuel sensor in the fuel tank. I called gm to see if they will pay for repairs but have not heard a response yet. I think it is a safety hazard to have lights flickering and engine surges. Your best bet , take it to a qualified repair shop.
They need to step up and face the cheap parts in their cars, and give us better customer service. Then it should go out after a few seconds. We notice it when driving to work in the pre-dawn hours and it occurs most frequently when we let off the gas to slow down. I have no idea how fast I am going and how much gas I have left in my tank. After that each gauge started dying one by one. A replacement dimmer or bypassing the current one and adding a resistor should take care of it.
Thanks, Dave Sounds like your alternator has some bad diodes. If your vehicle is equipped with an oil life monitor system then change it when the system tells you too and reset the oil life monitor. Today was driving home and the oil pressure gauge was pegged at 80 all of a sudden. I have noticed the battery gauge fluctuated while this is happened. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle. I was told that this was normal.
After checking for recalls I see now there have been alot of complaints with this issue in the same year vehicle but no recalls. Since July 5, 2009, the fuel gauge dial fails to display the correct amount of gasoline in the tank. I have had the air conditioning recharged, to no avail, it acted like there was a leak somewhere. The vehicle was taken to the dealer where it was found that the instrument cluster had failed and needed to be replaced. There are thousands of complaints on the internet from angry owners describing speeding tickets, running out of gas, odometer failing, dashboard lights dimming and warning lights appearing. Very annoying and scary, not knowing how much gas you have or how fast your going.
This should drain all residual power out of the electrical system and in turn reset your computer and all lights. The approximate failure and current mileage was 48,000. The contact also mentioned that the fuel and temperature gauges failed to operate. Only our bail out money. When closed they depress the pin which breaks contact.
It also revs by itself, even in park and will go forward slightly when it does surge. Then the speedometer started sticking. If chevy does not issue a recall for these we will not ever trust chevy products again. I believe it is a problem with the cluster. Fuse box under left rear seat. If this actually is your problem.
