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:
The manufacturer had a service campaign to replace the gear oil in the automatic transmission,s final drive (differential) with synthetic oil. There should be a tag on the transmission dipstick if this was done. (1991)
Cold-starting problems:
Hard starting and rough running after cold soak in cool (45-65 degree) weather should be fixed by a replacement coolant flange that includes a temperature switch. (1990)
Electrical problem:
The turn-signal self-canceling cam assembly fails, and redesigned parts are required to fix it. (1990-91)
Fuel gauge:
The fuel gauge stops working because of problems with the sending unit which may also stick or make clunking noises. (1990)
Fuel pump:
Loss of power and backfiring caused by a clogged screen (which was later eliminated) in the fuel distributor. (1990-92)
Mirrors:
The power mirror switch shorts out and should be replaced with a redesigned switch. (1990-91)
Rough idle:
The original O-rings on the fuel injectors will harden and leak causing idle problems. New seals are made of Viton rubber. (1991)
Tail/brake lights:
The brake lights quit working because of oxidized switch contacts; the interior lights stay on (or won't come on) due to faulty door jamb switches; the truck light stays on (or won't come on) due to a faulty switch. (1990-92)
