so my 02LS problem is with the temperature control module, steering wheel controls, and the homelink. none of them work. Occasionally I am able to smack the top of the dash until I see light come on on the temperature control then everything starts working again, I have check what I think is the common ground located to the right of steering column (I'm unsure though) and it seams fine, any advice as to what this could be?

side note when I use my blinkers they turn on like hazards but are faded on both sides, could these issues be related?

I have cheeked multiple grounds and fuses along with replacing the head unit, and the hazard switch

any thoughts or advice is greatly appreciated.
