1997 XLS - Climate Control blowing fuses - Toyota Nation Forum : Toyota Car and Truck Forums

Anybody have any ideas? 1997 Avalon XLS with auto climate control keeps blowing the (10 amp) "heater" fuse - as soon as the Auto button on the climate control system is pushed (to turn the system on). If the fuse is replaced - all of the button lights on the A/C, blower direction, fan speed come back, and outside temp display comes back on, but the fuse blows again as soon as the Auto (climate control) button is pressed to actually turn on heat or A/C. Additional info - the A/C compressor is original, and has gotten noisy lately (bearings? clutch?), but I don't know if that would be causing this fuse to blow.

does the blower motor ever run? it could be seized. else a worn thru wire maybe.

check the compressor. Look around the pully and see if you see any melted black plastic. I'd say the compressor is blown.

First - let me thank both Jack Deth and stope4 for their ideas/suggestions to the (1997 XLS - Climate Control blowing fuses) problem. "stope4" nailed it - the problem has been 100% resolved by replacing the "A/C compressor". Apparently the compressor gets turned on automatically when the Climate Control system is first activated - and turned off if not needed. The compressor was likely drawing too much current, and blowing the (heater) fuse when the system turned on. -NHAvalonGuy

I'm a new owner of a '99 Avalon. Half way home from my new purchase climate control quit. I replaced the 30 amp fuse under the hood. No go. I tried and tried to find the 10 amp fuse that is supposed to be inside the passenger side kick panel. Is this the one that kept blowing? I cannot find this fuse. Can you help?
Thanks

yes. Look at that fuse. If it's blown, I'm betting your compressor died. Also keep looking. It may be listed as blower. Something related to ac,

I still can't find the fuse behind the kick plate. Not that I can't find the right one...I can't find any at all in there. But, after more searching online I found a better diagram than the manual has. It still didn't show the one I was looking for. But it did show another fuse block the manual didn't, located near the drivers door. There's a 10 amp there labeled heat. Sure enough, it was blown. I replaced it, the outside temp showed when I started the car, the a/c didn't come on, the outside temp disappeared, and that fuse was blown again. Rats! Compressor, huh?

I found this on another forum
"If you're having problems with this fuse and the AC not working and the outside temp indicator going out, try replacing it with a 30 amp fuse. Toyota ... knew the AC amplifier was defective but used them anyway."

Anyone have any thoughts on this? Obviously if the compressor is blown it won't help. Sounds like he is saying this might be a fix for it if it's a bad amplifier. Sounds like a risky idea. I don't want to burn anything up.

yeah. well pull the plug off the compressor, put another fuse in then try again. if the fuse blows, it was not the compressor.

nothing personal but this is a fine example of depending on books, to the point of abandoning the ability to reason. and that is the product of the way people are conditioned, now. what will happen if, one fine day, all the books are taken away?

whatever it is, it won't happen to me!

Sorry, I thought you saying the kick plate was the same location as the fuse panel by the drivers door. I didn't know there was a fuse panel by the kick plate. Anyway, sounds like the compressor. pretty easy repair just buy a new oem from an after market seller. I wouldn't buy anything else but that's just me.
