Scenario: 200 mile round-trip (each way).

Weather: Winter 28-35 degrees F.

Climate control system: works great each way for first 30-40 miles, then blows super hot air from all vents for remainder of trip.

Result: Driving with front and rear windows down in dead of winter to keep interior below 90 degrees F.

Switchology: Doesn't matter, any setting produces same results. Have pulled and inspected solenoid valve inside mono valve multiple times, no tears in rubber, looks OK (new one on order). A/C switch assembly pulled, cleaned, checked. Works perfectly at dealer, he swears all is well.

Requirement: Any and all advise on how to fix climate control. Has been recurring problem over last year, no one can fix. car.
