i got the blower back on my truck after steig. had to reclearace it.it was great.................for about a week.weather was nice yesterday so i decided to go for a ride.it's back! i know some of you other guys have had this problem.have you taken yours off and sent it in each time or left it alone to see if it will reclerance itself.my truck is a daily driver and i am on thin ice now when i come to borrowing vehicles to keep taking this blower off to have it serviced.when i picked it up they said if it makes any more noise just bring it back in.with leads me to belive this is not an uncommon problem with their ported blowers.i am statring to get really pissed off with this truck!
