SUBJECT:
Air Conditioner Compressor Controls
MODEL:
E30
Situation:
Vehicles produced 1/88 and later are no longer equipped with the Compressor Enable switch (located on the lower and center air distribution slide levers).
Consequently, it is not necessary to open the air distribution slide levers for the A/C system to operate.
Evaporator ice-up is prevented by an evaporator temperature sensor and regulator in contrast to the evaporator temperature switch equipped with a capillary tube used previously.
The first edition 325i Convertible ETM reflects these changes and should be used on all late production E30's when diagnosing a compressor control problem.
