2002 Mercedes-Benz C-Class C240 4dr Sedan (2.6L 6cyl 6M)
Picked up our new C240 8hrs after arrival at dealer Thurs. Wasn't ready as promised. Heater wouldn't work.
Called at 10am next day as instructed. Car ready.
Arrive 12:30pm and pick up car.
Minutes away from dealership, turn heater on full blast. Thirty minutes later arrive at my office and cold air still flowing.
Therefore, can assume one of two things: dealer never fixed heater; dealer fixed heater and it broke a second time before driven off the dealer's lot.
