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.
Air conditioner:
If the air conditioner gradually stops cooling and/or the air flow from the vents decreases, the computer (PCM) may not be sending a signal to the compressor-clutch relay to cycle off, which causes the A/C evaporator to freeze up. (1991-94)
Alternator belt:
Deep snow could knock the serpentine belt off the pulleys of a 3.0-liter engine. Installing a shield should prevent the problem. (1991-94)
Automatic transmission:
Bad seals in the transmission lead to premature friction-component wear, which causes shudder when starting from a stop, a bump when coasting to a stop, and slipping between gears. (1993-94)
Automatic transmission:
If the transmission shudders under light to moderate acceleration, the transmission front pump could be leaking due to a worn bushing. (1990-94)
Engine mounts:
The motor mount on the left side of the engine tends to break. (1992-93)
Oil consumption and exhaust smoke:
High oil consumption and smoke from the exhaust at idle and deceleration on 3.0-liter engines is caused by exhaust-valve guides that slide out of the heads. (1992-93)
Rough idle:
2.2- or 2.5-liter engines may idle rough or stumble when first started below freezing temperatures unless a revised intake manifold (with an "X" cast into the No. 1 runner) was installed (1992) or a revised computer (PCM) was installed (1992-93) or the computer was reprogrammed (1994).
Transaxle leak:
41TE or 42LE automatic transaxles could take several seconds to engage at startup because of a problem with the valve body. (1993-94)
