I really know very little about cars, and do not want to damage anything on my Lexus. I have a 1992 LS400.
I have read several topics in here about the heater control valve being stuck. My heater is not working, and at one point the Toyota dealer told me my heater valve was stuck (either open or closed?). He did something, and it worked for like a day and blew hot air, but then it stopped again.
My car has at the firewall, a little manual lever with a wire - which I think is where the heater control valve opens and closes. I do see when I cycle my air conditioning system from low temperature to high, that the little wire does move a little in and out, but does not change the lever position. I also hear a noise inside the car when it is probably trying to open or close the valve.
I tried putting a little lubricant on the wire, but still it does not fully open or close.
Can I manually move that little lever (arm) at the firewall to pull the wire in or out, or will that damage something? I am thinking if I can pull the wire out manually and put more lubricant on it, maybe it will start working? Or at least if I have a manual way to get heat by moving that lever up or down, that would be an option until I can get it fixed.
Any help is appreciated! :)
Thanks,
