My HVAC control lights wont turn on when I turn on the parking lights or driving lights and the light for the clock turns on but again when i turn on the parking and driving it turns off...I found out that by slapping the waterfall real hard they turn onbut any tips on what could be wrong???

 

It's been covered. I had the same problem, and this worked like a charm for me. While you have it open, you should swap your led's out.

Thanks man I tried searching but couldnt find...Im going to attempt the fix hope I dont screw something up

 

It's easy, just heat the contacts while you press down on the chip lightly. Remove the heat and still hold it down. Count to five, release, rinse, repeat... You probably don't even need to add any solder.
