problem #2

Instrument cluster failure on 2004 Chevrolet Trailblazer. Oil pressure and amps gauge malfunction. Mechanic quoted price $650 to replace cluster. Emissions failure paid dealer approximately $375 to replace emissions pump. Air conditioning mode motor actuator out; blower doesn't operate on high setting. Dealer quoted price $750 to fix air conditioner. Sporadic electrical issues-service engine soon light on-first time code read faulty thermostat cooling sensor, next it read faulty air mass sensor, another time it read faulty emissions sensor. Mechanic quoted price $40 per hour plus parts to isolate problem. A person could go broke before fixing possible problems, considering no accident occurred due to all these possibilities. Front suspension problems, hard to isolate. Paid mechanic $135 to replace right side inner tie rod end. Did not fix problem. Problem occurs when returning steering wheel from a right turn, front right side makes a single "pop" sound. Had to replace "burnt" headlight pigtails on front, and park light pigtail on right rear. Property damage is considered damage to vehicle due to the complaints listed.
