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:
The air conditioning may not work due to a defective switch on the main climate-control panel. (1990-91)
Dashboard lights:
The "check engine" light may come on when the car is started if it was previously shut off before the engine speed dropped below 1500 rpm. There is a repair that prevents it from recurring. (1993)
Engine misfire:
The engine may run on after the key is turned off due to a faulty isolation relay for the canister-purge valve. (1990)
Engine noise:
Valve springs have been known to break on the XJ6 sedan. (1990)
Radiator:
The radiator fan may not run, or may run with the key off, due to water entering the fan control module by wicking down the ground wire. (1990-94)
