ITS ANNOYING...this is a dumb question but where the hell is the fuse panel....?? i dont have and owners manual and cant find it... and last for now...is my heater control unit sometimes does not switch to a different area and the heat will be really hott then it will go cold for a few seconds...once in awhile and my rear defrost dont work....all these questions would greatly be appreciated for answers thanx guys!!

The wire to the coolant level sensor may be damaged or loose, or the connection may be corroded. You can also have air bubbles in the system, which should be bled out using the plastic screw on the top/side of the radiator. Remove the radiator cap and loosen the screw slightly. Coolant will drip out, so place a rag underneath. The coolant level should drop and some bubbles may escape. Add coolant until full, tighten the screw and replace the cap.

The logicon may have cold solder joints which cause intermittent problems. The rear defrost switch may have the same issue, or you could just be seeing it switch off after ~15 minutes (normal).
