When diagnosing an air delivery problem on a car equipped with electronic climate control, all tests must be performed with the programmer mounted in the proper position. Failure to do this may result in improper diagnosis and unnecessary programmer replacement. The programmer must remain in the vertical position so the check balls in the solenoids will properly seat.
