Replying to: donivanf (Oct 11, 2007 10:12 am) I already have the auto climate control but I wanted to mention that the complete service manuals on CD I found on eBay for ~10 or 15 bucks if I remember right (I bought them when I bought our '03 HL in 10/02).   Phil
#12 of 107 2003 Highlander no cabin heat by 1rodger Oct 22, 2007 (1:19 pm)
I have a Toyota Highlander that doesn't provide heat for the cabin. The engine temp gauge is normal, but I'm getting cold ambient air from the vents. I have been using the A/C lately but tried heat today due to a cold snap. Is there some system that bypasses hot water from the cabin? My wife was driving and she heard a "pop" and remarked that the car never warmed up, I drove it this morning and there was no heat in the cabin. The coolant level is normal. The thermostat must be working or the car would overheat if stuck closed, or over cool if stuck open. Replies to this message: derekgaddy (Oct 26, 2007 5:20 pm)

Replying to: 1rodger (Oct 22, 2007 1:19 pm) 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!!
#15 of 107 Windshield defogger problem by teresa72kcb Nov 25, 2007 (10:49 am)
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!

Replying to: alleycat7 (Sep 18, 2007 2:55 pm) 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.
#17 of 107 EZ Airconditioner fix by cpiper Mar 08, 2008 (5:51 am)
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!

Replying to: cpiper (Mar 08, 2008 5:51 am) 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.

Replying to: webgood (Mar 09, 2008 6:37 am) 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?
