Had the condensor checked and it hold pressure and full of coolant. Took to another machanic and they are stumped and find nothing wrong. Working on ride home last friday, 3 hours later driving home from dinner and no longer blows cold air. Any ideas before i have to take to toyota dealer to get resolved?
If it works sometimes but not others, the most common faults are overheating components (AC clutch, control relays, ) pressure problems (high or low pressure or sensors reading too high or low after they are on for awhile), or defective blend door or temp control system.
AC isnt complicated. It really hasnt changed much at all in 20 years, and didnt change for 50 years before that aside from what refrigerant is put in. the theory hasnt changed. If you mechanic was checking condensers for leaks, and didnt find them, Id suggest someone more skilled at AC work. Condensers are NEVER EVER intermittent problems. They leak, or they plug solid. Neither condition comes and goes. Your problem is in system pressures, or electrical control, or clutch. Period.
SOURCE: A/C will suddenly send out heat. Fiddling with knobs seems to help. What's wrong?
You have a broken wire connection between the temperature control knob and the circuit board behind the center dash console. Vibration causes the failure and once the control knob gets loose the solder connection fails.
For someone that knows how to remove the dash unit and can re-solder a couple of new wires this fix should take no more than 1 hour. Make sure that you apply loctite to the heat control knob spindle nut when you re-assemble it.
The dealer quoted me 750 dollars to fix this issue and I found out that it's a common failure for this year. I fixed mine virtually for free but it took some tools and about an hour of my time.

set the tire pressure to the door decal, check all the tires, including the spare.
SOURCE: I want to install Toyota OEM remote starter to my 2009 Venza.
Do not install the OEM starter - it only works from about 80 feet away and is quite problematic. I just purchased a new V6-AWD with the push button start and the dealer is taking the OEM start out as we speak and taking it for an after market starter.
If you decide to do it yourself (you'll need to be quite mechanically inclined for this install), check youtube as the poster above has suggested - but again I highly suggest you consider an aftermarket starter and save the money that I didn't.

I finally found the solution. It is actually detailed in the owner's manual but you really have to hunt for it. Look at page 450/451.
Step 1: Switch the display to the trip meter A with the engine running.
Step 2: Turn the engine off (but don't turn the key all the way to where you can remove it from the ignition).
Step 3: While pressing the trip meter reset button, turn the key to IGNITION ON (but don't start the engine). Continue to press and hold the trip meter reset button until the trip meter displays "000000".
