Turn signals/parking lights

[93sierrak1500]

Morning fellas. I currently have the dash off of my 1993 Sierra K1500 because I’m replacing the dash and fixing the blower fan. For a while, my parking lights have not worked and my turn signals have been blinking fast. Have replaced all bulbs for parking lights and turn signals. Anyone know how to fix this? Thanks.

I’m not sure if having the dash off is a good time to resolve those issues.

I have the dash off to replace my blower fan and am dealing with all that wiring at the moment.

I got that, just saying while that’s going on, it might not be the best time for a different issue. Other than when reassembling dash, make sure grounds are solid.

Fast flash happens when bulbs are blown or install led bulbs.
When you have fast flash did you confirm the front and rear are flashing?
