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 A/C fails to operate accompanied by failure of the temperature gauge, transmission-selector light, and the outside-temperature indicator just displays two dashes, but the system returns to normal if the key is switched off and on, requiring replacement of the A/C electronic-control unit. (1998)
Audio system: If the CD player stops working, but returns to normal when the key is cycled, or the there is cross-talk on the AM band, the company will replace the radio-tuner assembly. (1998)
Electrical problem: Using the wrong cigar-lighter element (wrong size for the socket) can cause a short circuit. (1998-2000)
