Help! I have a 1999 C70 convertible with warning light issues. It started a few weeks ago with the tracs and abs lights coming on sporadically. After reading postings I figured this was the abs control module. Yesterday, however, the brake light (not abs or parking brake) came on as well as the check engine light. The abs and tracs lights also came on yesterday, but not at the same time. In addition, the digital odometer was blank for a short time and then came back on with accurate mileage, and the climate control was blinking and the fan was on even though the air was turned off. I've also noticed a fan running for awhile after I shut the engine off at times. When I drove it today, there were no lights on or problems. Please help diagnose these issues as I think they may be related.
