Electrical/ turn signal dilemma

[luke_jones]

Guess I haven't done much but lurk and watch peoples build since I've joined, but now I am hoping someone can offer some help.

Several weeks ago I pulled my cluster to swap the bulbs for LED, while it was apart I cleaned all of the contacts on the printed circuit board/plastic. Since I've put it back together I have had a problem with my left turn signal. When you use the signal the relay clicks and the rear signal flashes, but the dash indicator and front light does nothing. Same outcome with hazards, neither the left indicator or front left light flash. Does anyone know what I could have changed that would only affect the front portion of the left signal/flasher? Seems like it would be a wire or connection point, but I'm not sure where to look, everything seems to have a good clean connection.

On a side note, more recently I began having issues with my low beams. They don't work....its not burnt out bulbs because when you flip to high beams all 4 lights light up. I replaced the dimmer switch, but that did nothing for me.

Any suggestions would be great, I've been googling and trying/looking at anything I can come across and haven't found a solution yet.

Oh...its an 85 Suburban for whatever that's worth. Thanks!
