Turn Signals Problems on Malibu, Impala, Alero, Cutlass, Grand Am, Monte Carlo, Saturn Vue, Chevy S Trucks, Chevy T Trucks, Corvette

If you have turn Signals Problems on Malibu, Impala, Alero, Cutlass, Grand Am, Monte Carlo, Saturn Vue, Chevy S Trucks, Chevy T Trucks, Corvette, read this post.

The GM vehicles above all seem to have a common problem with turn signals. The problem may show up as the following symptoms:

No turn signal operation
Rapid flash even though no bulbs are burned out
Flasher clicks even though turn signal isn’t on
Intermittent turn signal or flasher operation

The source of the problem is usually a faulty Hazard Warning Switch. Yes, you read that correctly. All turn signal operations flow through that switch and it seems GM may have under-engineered the electrical contacts in that switch. Some shops report that even after swapping out the switch, the problem remains and they must replace the entire turn signal mechanism (called the Multifunction Switch). However, dealers report extremely high sales of these Hazard Warning Switches. The dealer list price on the Hazard Switch is about $30. However, Dorman Products makes aftermarket replacements that are half the price of the GM part and are a direct fit for the factory switch. But, if you shop on Amazon you may find AC Delco parts (made by GM) for the same price as Dorman.
To replace the switch you’ll have to remove the bezels and trim panels. I suggest a subscription to Alldata because they show much better interior trim removal diagrams than eautorepair.net.
