Drivers signal flashes fast. New Bulbs!!

[Panner99]

Hello. I had a burnt out drivers signal light. Blinker was flashing fast. So I replaced the burnt out bulb. It fixed it for about 15 min. Then the flasher was flashing fast again. This time the lights were working fine except fast.. I then replaced all the bulbs. It seemed to fix the problem. Got up to go to work, Drivers side is flashing fast again!!!!! Get half way to work, flashes normal. Get to work and try the signal again, starts flashing fast. Its so intermittent. What the hell is going on.

BTW it is a 1999 Denali

Figured it out. Was the socket in the front signals. The bulb wouldnt stay tight. Bent the bottom connections up and presto!!!

This is also a common problem with the tail lamp circuit board on these YMM'S. JMHO and good luck.
