1999 Chevrolet Blazer lights problems

Filed Nov 7, 2012 · Electrical, Lights · 140,000 miles · ND

1999 chevrolet blazer lt - multifunction switch (common problem!) is malfunctioning. Turn signal/flasher relay is constantly clicking whether signals are in use or not -- unless the brakes are applied. Good sign of an electrical short. The cause of this issue is the grease inside the switch, applied at the factory, running from contact to contact. This switch includes the wipers, cruise control, turn signals, hazards, and can also cause vehicle lighting (headlights, brake lights) to malfunction. Many cases include non-working brake lights! Others have reported smoke coming from the switch as the contacts are shorted by the grease. I inherited this vehicle from my grandfather, who couldn't hear the relay firing -- it is the only indicator inside the vehicle that something may be going wrong. There are no visible indicators inside the vehicle letting a person know their lights are malfunctioning. As there is no recall for this year of blazer (though I understand other years have had the same problem recalled), I will be replacing the switch on my own. Dealer quoted the price for the part alone well out of my price range (nevermind labor), so I'm going to have to shop around to get the vehicle in safe driving condition. Thanks for reading. I appreciate it!

The multi-function switch in my 1999 chevy blazer ls is malfunctioning. During driving, the blinker sound is constantly clicking whether or not I am making a turn or enabling my safety hazard lights. When I apply the brakes on the car, the clicking sound temporarily stops. When I drive again, the clicking sound starts again. This malfunction gives the driver the false indication that their turn signals is on, when it is actually not on, and can cause an accident.

'99 blazer zr2 my daughters first car, she paying for herself. Has the most annoying blinker noise under passenger side dash. In research have found that 100s of other people are having the same very expensive fix. It consists of a multifunction switch with the cost of upto $700. I feel that chevrolet (gmc) should be responsible for some of this repair--it obviously is a problem with a design or a defected part. If you check the internet it is just loaded with people dealing with this. In addition to this that same year blazer seems to have some transmission problems and bearings at the 70,000 mil range.....something isn't right here. We just did the bearings for the $400 price tag. Please help this young girl, she is trying to the right thing, lets help her do it.

I have a 1999 chevy blazer with 89,000 miles and it seems the multi function switch is failing. My turn signal beeping does not turn off when I not using the turn signal. I heard this also will eventually cause a delay with the turn signal that could eventually be a safety issue.

There is a constant blinking noise coming from my glove box. When pressing on the break it quits. By looking up information on the internet I found out it is the multifunction switch. There were recalls on other years but not 1999 blazers. Its very expensive to fix. There was one on 1998 blazers I believe. I have a 99 chevy blazer. Has happened since I bought it.

Signal switch located behind glove box clicks erratically - this is the 2 nd time since I have owned the vehicle that this has happened - the first time was a $400 repair bill...I think I will try to let it drive me absolutely crazy before replacing it this time.
