Buick/Olds: Heater, buick roadmaster, 1994 buick roadmaster

Question
Hi, my mom has a 1994 Buick Roadmaster Sedan, and ever since she bought it the heater has never been hot.  Well, this winter the heater finaly quit getting warm at all.  It blows air, but pretty much it just blows!  What problems may be causing this to happen.  Oh yeah, my older brother added a new thermostat, but that didn't help.

Answer
What mechanical work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made.


In MOST cases your problem is with the A/C-heater PROGRAMMER that will need to be tested.
