Climate Control System - Air Delivery Diagnosis

Bulletin No. T 87-123
File in Group 1
Number 36
Corp. Ref. No. 711101
Date June '87

SUBJECT: IMPROPER AIR DELIVERY FROM ELECTRONIC CLIMATE CONTROL SYSTEM

MODELS AFFECTED: 1981-1987 RWD DE VILLE, BROUGHAM AND LIMOUSINE 1980-1987 ELDORADO AND SEVILLE 1985-1987 FWD DE VILLE, FLEETWOOD AND LIMOUSINE 1987 ALLANTE

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.
