Your car is OBDI. OBDII became mandatory on all cars and trucks manufactured for sale in the USA for model year 1996, even if they were built in 1995.

OBD2 started in 1996 I believe, so i would think anything made before that would not have OBD2.

Heater no working on 1991 buick regal 3.1


It probably has an airlock - so needs the air leting out of it.

If you have the bleed screw on the pipe that goes from engine to bulkhead, then, with engine cold, and heater turned to heat, start engine( KEEP CLEAR OF FAN / BELTS ), and undo bleedscrew to let out air. STOP ENGINE. Refill coolant to mark with antifreeze mix.

If this soes not solve problem, it could be more serious - either blocked matrix or if you only find steam regularly - it's a head gasket problem - requiring replacement.
