One problem related to dash wiring has been reported for the 1998 Chevrolet Cavalier. The most recently reported issues are listed below.
The wiring on my 1998 cavlier wore thrugh and shorted out ignition and other accessories. I paid dealer to make repairs the same problem has now happened to my daughter's 1998 Cavalier at about the same mileage the dealer she is talking to says the problem was caused by the clip that retains the wiring harness and they state the defect is not covered by the extended warranty, Chevrolet customer service refuses to talk because she has an extended warranty it seems to me that there is a problem with the way Chevrolet supports the wiring harness under the dash if in one family the same defect develops at about the same mileage, on the make, and model of vehicle. Others must be having similar problems.
