03 bonneville that only blows out heat once in a while


Could be a lot of things (i.e. thermostat, heater control valve...) Does the temperature gauge reach normal (1/2 way) temps?
Check to see if the control valve is working. Here's one way to do it. On the passengers side, remote the lower panel just under the glove box. Should be a couple of plastic pins holding it in. With the car running at normal temperature, move the hot/cold slider lever to HOT, then to cold slowly and see if the valve (located on top of the heater core) is moving. I "think" the heater control panel is vacuum operated and you may have a split in the plastic hose(s). Listen for a vacuum leak...
Good Luck. I hope this helps.

Engine coolant Temperature gauge fluctuates


Watch the temp gauge when the electric radiator fans come on. The temp sensor that controls when the fan comes on may be faulty.

My coolant fans don't work. What should I look for? I'm bringing it to a repair shop a mile away. Will it be safe to drive it that far? The temperature here is about 100 degrees outside now.


Hi,
If you start out with a cold engine, the Bonneville should not overheat traveling one mile, with out the A/C on.
If you are in stop and go traffic, roll your windows down, turn heater on high temp and high fan, and shut the Bonneville off at stop lights.
Watch the heat gauge.
The coolant fans not working may be a fuse, relay, or temperature sending unit switch.
Best Wishes,
Wayne

1997 Bonneville SSE, when the heater is turned on, only cold air


you may have a failed blend air door motor/actuator. this part will regulate the amount of air from the heater core depending on the temp setting on your electronic climate control unit. if it has failed, it will be stuck at the temp that it was last set at when it quit working. it is also possible the heater core may be plugged up, but using the gm recommended dexcool coolant and flushing it out every 5 years, it should not be plugged up. you can pull the 2 heater hoses off the heater core on the passenger side of the engine compartment firewall and see if the heater core is the problem. caution-do not use a high pressure air hose to blow through the heater core as this could damage it and cause a leak!

Heat blowing Cold when in drive. When in Park, it is warm


have you chg. any thing lately like thermostate? added any coolent to system? if not, thermostate could be stuck in the open position. if stuck open, setting still, it will throw heat, but moving coolent flows to fast and does not get a chance to get hot. if you did chg. thermostate it could have a air pocket in the system. and also adding coolent can create an air pockets too. you will know this when your traveling down the road and temp guage fluctuates up and down. witch means air in system.
