Four problems related to turn signal switch have been reported for the 1999 Chevrolet Blazer. The most recently reported issues are listed below.
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.
The multifunction switch has malfunctioned and caused a ticking under the dashboard.
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.
Consumer states almost rear ended when brake lights were inoperative. Third light works but other two work on and off. Dealer found multifunction switch is shorted out.
