climate control unit is not working... (1 Viewer)

[sweet trav]

on our 97 lc. I tried to adjust the air flow with just the vent on but nothing happened when I pushed the buttons. Then I tried the ac and still nothing.

Nothing happens whenever I push any of the buttons on the climate control unit...is there a fuse that might be out or is it something mechanical?

thnx,

Are you referring to the fan speed (could be your blower motor resistor), or the temperature mode (heat cold door stuck or the engine heater valve mechanism, can't remember the exact name of it right now sorry)?

well, today I installed our newly balanced rear drive shaft with new u-joints and all of the sudden the ccu works again! I knew it had something to do with the rear drive shaft!

since his problem is fixed ill hijack the tread if at all possible.

I can not choose between hot and cold I can not seem to get the right set of search words to find what I need to do.
When I slide my temp control toward cold I hear a clicking under the dash. Slide to heat, clicking stops. So I know the clicking is from the controller trying to change between hot and cold but it is stuck on heat.

How do I start trouble shooting this??

if it's the auto climat control, it's probably the control box under the dash above your right foot. Mine worked on and off and on and off for ever. Dealer had the truck for 3 weeks couldn't figure out the issue.

I'm dealing with the same issue with my LX 450 which is auto climate. I have tons of electrical issues though. Where could I find a replacement box that is under the dash (besides through the stealership)? And also, is there something cheaper to check? I have checked the valve against the firewall, and it's not that I do not? Where is the blower motor resistor?

CDAN is a good source, so is Toyota of Dallas and ACC - or you can try a junkyard unit - I did 3 years ago for $125 - and haven't had any issues since. The price is rediculous as it likely cost toyota $20 (if that).
