#186 of 217 A different heat problem with Avalon
Feb 07, 2009 (2:41 pm)
I am,according to the folks at Toyota,the only person in the universe with this problem. We bought a brand new 2007 Avalon Limited in May 2007. From the 1st time using heat the car will on occasion kick the heat to maximum Then we have to hit the buttons to bring back to normal. It has done it several times on say a trip from Buffalo to Syracuse-then it will go weeks and weeks and not do it
Of course it never acts up for the dealer!! The arrows indicating where the heat is going will change by themselves and then last week the radio came on by itself! ( This week the windshield washer bottle emptied out because the bottom hose fell off. Dealer fixed that)
Anyone experience any of these? Otherwise the car is great actually.

I believe it's normal for the arrows to switch automatically from the floor and dash vents depending on the temperature required. I also had the same problem with the windshield washer bottle and there is a TSB (TSB BO 008-07) for the 2007 Avalon and it involves replacing a hose, joint and related washers. I haven't had the mystery radio come on by itself. If you have the heat set to automatic the fan will increase in volume as the car warms up but it should automatically decrease when the desired temperature is reached. I did have one weird problem - the heated seats stayed on even when the switch was in the off position and of course it couldn't be duplicated at the dealership. It only did it one day and it's been fine ever since. I hope they find out what's causing your problems.
#188 of 217 98 avalon xls blower runs on low

my avalon recently started running on low even when i switch it manually to high. sometimes it will go to normal speed then to low and repeats. no pattern to it just random. checked the blower and it's fine. i've read that the xls does not have a resistor but then i have no idea what would cause this. any ideas would be greatly apprecciated.

Anyone know if the '95 Avalon XLS has a cabin filter behind the glove box, like later models?

Not it doesn't. That's comes in about 1999 on the Avalon I think.
#191 of 217 AC Blowing Hot air

A/C blowing hot air. Going to take it to an independent shop, but wanted to see if there are any issues that might cause this besides needing a new compressor. Any Ideas??
#192 of 217 Heater problems
Oct 08, 2009 (4:09 pm)
I posted this question in the 2008 Toyota Avalon section and then came upon this forum. So, here it is again.
When I set my Avalon's passenger temperature to anywhere between 74 and 80, the back vents blow out air at 107 degrees which makes it impossibly hot for anyone in the back seat. The passenger in the front has to freeze or the back seat passengers have to burn up. Anyone else having this problem?

I don't think its a problem at all. From what I remember from when I had my '06 Avalon that is just the way it works. FWIW I never had to set the heat above 68-69 or the car blew me out of there it was so hot.
#194 of 217 Little heat in 1997 Avalon XL
Jan 12, 2010 (4:57 am)
I am hoping someonce can help or has worked through this. My wife drives a 1997 Avalon XL. Has about 130k. The car gives very little heat. The engine does not overheat. The AC works fine. However, you have to be driving for a while with airflow on recirculate to build up any significant heat. I've had the timing belt and woater pump replaced just this past summer (July 2009). I use long life coolant whcih is reccommended by the dealer and there are no coolant leeks.
Please help! My wife hates the cold!!

Here's some general thoughts, others will have to give you more exact details. Your cooling system works, the car operates and does not overheat or leak. That means the warmed coolant is not getting to the heater core that allows the heat to be blown to the interior of the vehicle.
There is a control valve that diverts coolant to the heater core. This valve is not opening. Or the hose to it is stopped up due to age. Or the heater core is plugged in places with residue. Or the control switch is not telling the valve to open. Or the return line from the heater core is plugged. Or a combination, this is a 13 year old car. (It's not the coolant or the water pump.)
A coolant flush with the new pump should have revealed the problem. But if you just had this work done and have never had the problem before, the repairs may have caused the problem. In order of simplicity, step one might be to ask the dealer to check his work and see that all lines and wires have been properly re-attached. After that, check the valve and hoses. Last, look to the heater core. Hope this helps...
