well it looks like i have a intermediate problem with my turn signals... they will work sometimes and then not....i can hit the 4 ways and they work and then hit the signal and it will work...not sure where to start looking for a problem...anybody else had this type of problem?
The problem is in your hazard swithc. The turn signals are wired throught the switch and GM had a bad run of switches (imagine that ).
Two ways to fix it.
1 replace the hazard switch ( dash board will need to be removed it goes in from the back)
2 This is the one I use. When they don't work lightly hit above and to the left of the hazard switch with your fist. Works every time for me.
My 99' does the same thing. I turn on the flashers and then the blinkers work again but this does not always help. Sometimes after driving for long periods of time they just won't work. I found the switch at GMparts Direct for $20. It is #10359036 for my car.
