Brandon, I believe that there is a refill and bleeding guide posted on a sticker on the inner fender or underneath the hood. At least there was on my 98.

Yamae, do you happen to know the failure mode of the Multiplexer computer? Does the LED knock out some drive transistor? And finally, are there any schematics of the MPX? I would love to take a look...

You have sinned 808 times my son. Repent, and your dome lights will again work. ;-)

Yeah, I think you found the 'smoking' gun. The grease worked out of the RH (passenger) side axle and the CV is probably shot. You can buy a new axle for about $50 but there is a core charge of about...
