I have a 1998 Camry LE with 95,000 miles. About 3 weeks ago the heater was not working properly and I took it to the dealer; $650 later I had a new thermostat, water pump and timing belt. A week later I took it back again because it was only warm at idle but hot when driving. They kept it a few days, said it was an air bubble and sent her back. Last week I took it back again because it still is only warm at idle (I have a remote starter since I have no garage and it usually heats right up) but hot when driving. THis time I was told there was a blockage in the heater core and it would need to be replaced, so a week later and another $650 I had the car back. Guess what?? I still have the same problem! Has anyone else had this problem or have any input? I would really appreciate it. I am going back to the dealer next week for them to try again. Thanks - Snarl
