I am experiencing this anomoly on my '98. Operation of the right front window and all door locks is intermintent. Commands from either drivers console or passenger side fail to actuate the mechinism. (sometimes does, sometimes doesn't)
Profuse cursing also has a demonstrated failure to correct this problem.
I extracted the right side switch console unit and all connections are clean & servicable. Interesting to note that when the door lock is commanded from the drivers side, the right side "clicks" as if attempting to operate.
I will be extracting the drivers side switch console next for a closer inspection.
I called the dealership for unit replacement costs; drivers side=$200, passenger side was $108. (fronts). Will check E-Bay for lower cost replacement units first.
