Took mine in Passenger window would come off track 6 inches from the top. Drivers has always been slow. The isuzu dealer kept it all day called me and said they would order the " regulators for both. One week they kept it a day replaced the regulators, they must have done something , it smelled like glue afterwards. Next day passenger window would not go all the way up with out help, driver was creeping slow. Got a follow up call and told them, They came and picked it up kept it all day, gave me rental as they investagated the fix . Next day completed it . they said shimming was the key. Now both are very fast. no Problems So far. But the next day the cd changer ate the cds. One week to order and 4 hours to replace .I wonder if I'll see those discs again?
