a/c panel is flashing on my 90. a/c lines have been removed. i can still turn on the blower when it stops flashing and change the blend door. what causes it to flash. never seen this before.
the truck has been converted to carb and found that the ecm is missing. is it tied to that?

My running light fuse keeps popping. I recently changed taillights to a different pair of stock lights. I also have a visor and LED halo rings wired into my running lights, and LED gauge lights. I'm trying to go through everything but does anyone know what could be causing it in the meantime?

Can someone please tell me what the little buttons to the left of my steering column do?

It lights up this red light when I press the down button.

There's really no way to know unless we were there in person

So this aftermarket? Maybe installed by the last owner.

Anyone know why after I installed 1157 led parking bulbs in front, why now my led turn arrows stay on inside truck?? When I installed bulbs the right way in socket and then turn park lights on there not that bright. But when I turn bulbs around the wrong way they get way brighter but with both ways of flipping bulbs, the inside arrows stay on no matter what. Any ideas?? Led bulbs are from ebay if that helps.

I installed led switchbacks and when all the lights are on they light up white and when I give a signal the amber comes on and flashes but the white stays on and just washes them out. I also installed an led relay so there is not hyper flash. Im just wondering if there is a way to get the white to go out when signaling so that the amber can actually be seen.

I cannot turn back my key from the run position. I do not have power for my radio, heater, windows, PSOM, or wipers. However if I pull down on my steering wheel power is restored for as long as I hold that position. My deduction is that a wire is sheared or pinched. Is there a way to access wiring without pulling the wheel?

Many thanks
