Picked up my car on Saturday. 1989 Black/Black 96K miles. Great five hour drive, runs great. I'll post pics soon. I've got a couple electronic questions. 1. My dimmer on my headlight switch does not work, is this a common problem and does it control the Onboard Computer Light? My OBC light is super dim. The computer seems to work but I can barely read it. 2. My windsheild washer fluid check light keeps going on even though I filled it completely. Can I fix this? 3. My speedo is off by 5 mph but I beleive this is because the wheels that are on there are 205/50/15 instead of 205/55/15. TIA. Glad to join the team.
