Heating problem
Hi Board!!!
I have a 95 Camry or should I say it's my wife's car therefore I don't drive it but recently when I did I noticed that when the heater is on and the rpms are low the heater blows out cold air but when the rpms increase the heater blows nice hot air until I increase the heater fan to high and then again it begins to blow out cold air. To make this long story short has anyone experienced this and does anyone have a solution?

RE: Heating problem
sounds like thermostat, but you may have bad water pump. Does the temp gauge go above normal operating level?
Before you get too involved, check water level. You may simply have air stuck in the system.
good luck

RE: Heating problem
Thank you geokor. I thought it was the thermostat at first so I did replace it and the same heating problem. The water pump was replaced about 5 years ago could one go out that fast? I didn't think about there beingair stuck in the system. If there is air in the system How would I remove it?

RE: Heating problem
try burping the cooling system before you start throwing parts at it.
its quite easy.
on a level surface, with the engine cold, remove the radiator cap. if you do this while the car is hot there is the possibility of steam burns
top off the coolant in the radiator. now start the car and crank the heat all the way up inside. return to the radiator, and squeeze/wiggle the upper radiator hose (should be to your right). if some coolant sploshes out, dont worry. if there is a bubble in the coolant system,you may begin to see a few bubbles each time you do this. continue doing this intermittantly until the car has reached operating temperature (on the dash gauge should read about halfway between h and c). if all is well with your waterpump/ tstat you should have heat.
keep in mind that the reccomended time for changing the tbelt/waterpump is 6years or 60k miles. id say its time to get some service.

This sounds more like a flow problem. If you aren't having overheating problems then I would check the heater by-pass valve for proper operation. It is located on the DS firewall. When you turn the heat to full the valve should open all the way. Get someone to turn the heat up and down while you look at the valve's operation.
