Need to get my heater core and blend doors replaced on Grand Cherokee. Also passenger seat heat system needs to be checked. Warranty is now expired, so need a good non-dealership mechanic. Both dealers I went to estimated ~$1700 for heater core and ~$750 for seat. Friend has an ASE mechanic in Houston who will do the core and doors for $525, seat for $325. I'd rather not drive to Houston to do this.
