Hello,

I have heater problem in my Pontiac Bonneville 2000; when it was on high and the inside car was warmed, the heater started to make noise. The noise will cease once I turned down the heater. Does anybody know what is going on with the heater? Thanks for the helps.

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