Pontiac Repair/1990 pontiac grand prix turn signal lever replacement


QUESTION: Hi there,
I have a 1990 Pontiac Grand Prix 6 cyl
I am having issues with the turn signal,
when i turn it down (left) it works fine, however
when i turn on the right (up) then its some kind of a loose connection.
I can barely touch it and the right blinker turns on, but when i lift it all the way like its supposed to be it only works for a split second then it turns off.
So my question is do i replace the whole lever or is it the turn signal switch that needs replacing?
Thank you very much,

ANSWER: Hi Stefan:

it is more then likely a bad switch it's self not the lever. it could also have a short ckt. in the left side turn signal. it will act that way or flash super fast. you havn't changed any bulb on this have you? incorrect bulb type will cause odd issues.  do this turn on the 4 way flashers and walk around the car and make sure all the bulbs are working and none are dim/out or brighter then the others is they all flash the same the issue is with the t/s switch. if you have one coner of the car especially on the left side look there first for an issue. good luck :-}

QUESTION: Hi there thank you for your time.
When I turn on the hazard lights then all blinkers work fine, i only have a problem when i try and turn on the right blinker, it only works the first 2 millimeters then as i turn it all the way up it stops working.

it's probably the switch if everything else works including the opisite side turn signals but just the one side is not working it's the switch if the hazard lights work they use the same ckts and bulbs the only difference is the power path though the switch.
