Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Automatic transmission:
Harsh shifts into second or fourth gears on cars with automatic transmissions is probably due to a missing or defective air-exhaust plug. (1990-94)
Blower motor:
If the blower motor is noisy or jams and blows the fuse, or if the inside of the windshield fogs up, there may be a water leak at the plenum. (1990-94)
Engine misfire:
Stalling at idle, no air conditioning, and a "check engine" light could be caused by a bad ground. Splicing a ground wire into the original one leading to the computer might solve the problem. (1990-94)
Manual transmission:
Gear clashes or grinding when shifting from second to third gear is corrected by installing beefier synchronizers. (1992-94)
Water leak:
Water on the floor from what appears to be a leaking heater core is really a leaking heater valve. (1990-94)
