I have a similar problem. I have electronic climate control and I only get hot air if my controls are above 77 degrees or so. Any idea what the problem is? I hate to go to the stealership. Help!!

Windshield defogger problem by teresa72kcb

2001 Toyota Highlander - instrument panel lights for clock, AC, air intake won't light up. When heater-defogger is turned on, hot air blows out air conditioning vents, but no warm air comes out windshield vents. Makes for very dangerous driving conditions in cold, wet weather. Help!

I have an 05 highlander that I bought new and I am having that trouble right now, however mine has now stopped working on the heat side. Guess what, it's the control panel and it is going to cost $740.00 for the part alone. Go get yours fixed right now if it is under warranty.
 
I am trading mine in asap for something else. With the other problems that I have had, I will not be getting another Toyota.

EZ Airconditioner fix by cpiper

The other day, the A/C started blowing hot air and the A/C wouldn't work. Another $600 bill I thought... A friend recommended a small garage so I took it there. The mechanic checked the temp. of the A/C pipe in the engine compartment and found it was cold. He pulled off the large dial..the one going from hot to cold... and found that the switch behind it was loose and on hot air. He tightened it up and the A/C engaged.
Cost:0$ but a $20 tip!

This appears to be a major source of complaints, particularly as the HL's get older, and has been addressed in other posts, but maybe not so clearly. The temperature control knob in the center begins to feel a little "wobbly". It should be nice and firm when turned and you should slightly feel position indents or stops as it's turned. Pull straight-out on the knob, it comes right off, and tighten the retaining nut on the control post, push the knob back on. Same for the airflow direction knob to the right.

I have an '04 Highlander. I will get heat intermittently, even though the engine is hot and the temperature knob turned fully to the right. Turning the knob to cold and then back to hot usually works, but often it takes 2 or 3 times. Sometimes heat is coming out, and then is just goes cold. The knob isn't wobbly. Any ideas?

Sorry kleutster, I don't know enough about the inner workings to venture an intelligent guess. But, just for the heck of it try checking the temp-control assembly...grab the knob with all your finger tips and pull straight out. It comes right off and will slip right back on. Check the assemble to see if it's locked-down in place with the nut. Beyond that, off to the Toyota or import car specialist. Regards, BGood

Highllander AC/heat control problem by ladyk1

I fixed my Highlander's temperature control problem, thanks to looking it up and finding out about the wires that broke. Long story short, I called Toyota to see if there were a lot of complaints about this being reported. There are web sites everywhere that address this particular problem, yet Toyota doesn't acknowledge a problem. I would like to suggest that everyone who has had, or is having this problem, to please call and report it. The number is 1-800-331-4331. Perhaps they will design it better next time, or maybe even recall it (but I doubt it). Anyway, I saved about $800-$900 by fixing it myself, rather than take it to Toyota. Thank you to all who posted info about this problem.
