1997 GMC GMC TRUCK User Comment / Complaint

I own a 1997 gmc yukon that has ongoing, severe problems with the windshield wipers. they either do not work at all or they run continually in an erratic manner and will not turn off. i learned that gm issued a recall (#03023) in may, 2003 for 1994-1997 gm trucks and suv's, including yukons, due to this exact problem with the windshield wipers. the recall was to replace the windshield wiper motor circuit board and cover. i took my vehicle to north county gmc in escondido, ca, and left it to have this repair performed. i later received a call stating that my car's vin number was not included in the recall. in fact, the service department acted as though they knew nothing whatsoever about any recall. i advised the service department that the documents i obtained on the internet regarding the recall were in the vehicle. i asked them to review the papers and find out why my vehicle, as listed in the paperwork, was not included in the recal when i am experiencing the exact problem that prompted the recall. the only thing that the dealership would tell me is that my particular vin number is not included in the recall and it would cost several hundred dollars to fix the problem. i do not understand why gm would issue a recall for my exact vehicle, 1997 yukon, because of the exact problem i was experiencing, and then refuse to perform the repairs. why would my vin number exclude me from this recall? i am very frustrated with gm's recall policy and north county gmc's actions in this matter!l
