I have a 1990 Buick Lesabre. Recently it has had a number of things that have needed to be fixed/replaced.

Yesterday the Radiator was replaced. However since they replaced the Radiator the heater doesn't work anymore. It worked fine before the replacement. What might cause the heater to stop working?

(Note Engine was replaced about 5 years ago, and the mileage above may not be correct for the engine but is what the speedometer reads)

Did you meant the heater won't come on or it won't get hot inside

The blower comes on for the heater but the air is cool. Doesn't seem to heat up at least not in the half hour I left it going.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
