I'm having an electrical issue where if I start my car with the climate control fan on, the fuel mileage display doesn't power on and the automatic headlights don't turn on. I can however turn my headlights on manually. If I start my car without the fan on, everything else USUALLY works. If I start the car with the fan on and turn the fan off after starting the car, I hear a clicking sound from a relay to the left of the instrument cluster under the dash somewhere. About one second on, one second off. I took the left access panel off and there is a gray relay and a black relay. I felt both of them and I believe the clicking is coming from the gray one that's above the black relay.
if I turn the fan on all the way the fan will run but the fuel mileage display is still off. When the fan is on all the way the air conditioning is also on and I can't turn it off. Upon turning the fan back off the display turns on very dimly and takes a while before it gets brighter. Sometimes the fuel mileage display gets stuck on its startup however and all indicators are lit up
it used to be this problem occurred every few weeks and if I hit the steering column or dash it would start working. The problem is happening most of the time now and the usual stuff doesn't work anymore. I was hitting it while driving today and the display actually went off. So now my usual fix is actually screwing it up more
I also have a problem with my BTSI which may not be related but I figured I'd throw it in there too. It doesn't let me out of park unless I push the manual over-ride in on the console
I also noticed that there's this aluminum finned electrical box or device on the left hand side under the dash as well and it's pretty hot and the wires coming out of it are really warm. What is this?
this is a 2002 Grand Prix GTP 40th anniversary with about 167xxx miles
Surprisingly the car drives okay I just can't use my climate controls
This is getting to be a PITA. Thanks
