There was a recall on our 1995 s-10 truck and our 1998 Chevrolet blazier has the exact same part and is also defective also. The windshield wipers on our 1998 blazier donot work some times they won't work other times and sometimes they won't shut off. Our gas pedal sticks when you try to take off.
Transmission replaced after 2 years of hassle, new transmission shifts hard but dealer states all transmissions run that way. Turn signal/windshield wiper module replaced twice, turn signal continued to click after turned off, windshield wipers turned on by itself. Driver's mirror replaced twice due to vibration and continues to vibrate, dealer refused to replace a third time due to a bugshield being installed even though mirror vibrated before bugshield was installed. Vehicle was bought at grubbs Chevrolet but has been serviced for the past two years at lowe Chevrolet in waynesville mo.
Turn signal continued to click after turn signal was shut off -- had to get multifunction switch replaced. On a related note, windshield wipers continued to run after shut off. Occasionally the windshield wipers still perform erratically with the replaced multifunction switch.
