2000 buick regal winshield will not defrost i have ice inside and out


If you are getting heat inside the car, the defroster should also work. There is a control switch problem that doesn't switch to defrost from heat, or the compressor for the air conditioner is not functioning...it provides heat for defrosting as very dry air to the heater box.

Need to replace the heat sending unit on 1991 buick regal but cannot find where the part is located can you please advise me of where the heat sending unit is


If you mean the engine temperature sending unit, it should be on the cylinder head and has a single wire attached to it. It looks a little like a miniature spark plug with a black insulation. To simplify your search, buy the new one and look for the same thing on the engine.

I have a 1991 buick regal and when i turn the heat on only cool air blows out. it doesnt leak on floor either as if heater core was out. what should i do


Check that the heater core is not plugged by feeling the 2 heater hoses going into the firewall. If they both get hot, then the heater core is not at fault.

If they are cool, then the heater core is plugged then the heater core will have to be replaced.

My heat blow cold some body told me i need resistor on a 91 Buick regal unlimited where do i find it


the resister only changes the fan speed
if you have not heat
first check coolant level if it's down then you have a leak that will cause no heat if it's ok
then run the vehicle and make sure the engine temp gauge reads about half if not change the thermostat if the engine temp is ok
then grab the heater hoses see if they are hot then the heater core is plugged and if the heater hoses are hot
then there is a problem with the heater control head
hopr this helps

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.
