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.
Blower motor:
The blower motor fails if the spark plug wires are routed too close to the blower-motor housing. (1994-97)
Engine noise:
A rattling noise from the engine at startup is often caused by automatic-transmission pump starvation or cavitation, or a sticking pressure-regulator valve. (1994-95)
Fuel odors:
Leaks in the vapor recovery system, due to excessively short hoses coming loose, causes fuel odors inside the car. (1997)
Oil leak:
Beware rear main seal leaks on Northstar engine. (1996-99)
Oil pump:
Low oil pressure may result from debris caught in Northstar engine oil pump pressure relief valve. (1993-94)
Steering noise:
The upper bearing mount in the steering column can get loose and cause a snapping or clicking, requiring a new bearing spring and turn-signal cancel cam. (1994-96)
