Default electrical problems? rpm guage doesn't work...and

and , my check engine oil light keeps going on and off..... my rpm guage sometimes moves up and down periodically. Overall, everything else seems fine, and the engine runs fine. I have 120k....and just noticed this problem after spilling coffee TODAY down the instruments cluster (radio area). Is there a relay or something back there that the coffee may have reached? thanks, Jeff

Default Pull cluster, unplug stuff, clean contacts, plug stuff back in.

I think you already answered your own question. Oh, and one piece of advice...DON'T SPILL COFFEE IN YOUR INSTRUMENT PANEL!!!

^^^ What he said. FYI, that RPM thingy is called a tachometer.

Default I tried cleaning the cluster contacts, but that didn't work...any other suggestions?

If coffee did manage to go down the top vents, where would it go? Is there a circuit board back there .....I did remove the cluster, and cleaned - didn't help. I'm wondering if I have a ECU board problem, since my brake pad wear light started acting up for about 3 weeks prior to this problem....and the pads are fine. Would anyone be willing to swap ECU to see if thats my problem....I'll give you some money. thanks,

Hmmm...I think you need to have that checked out by a proessional at this point.
