The heat and ac stop working at low speed and idling

SOURCE: 2001 Toyota Sienna AC stops at idle.

Tell Kwik-Kar that they are full of ****. The Sienna A/C is virtually bulletproof, and I have NEVER had to "replace" a system. That being said, I would guess that the freon charge is low. Open the hood, turn on the A/C and look at the sight-glass next to the radiator. Do you see any bubbles? If so, the freon charge is low. Get a qualified A/C tech to hook up same A/C gauges & read the high & low sides of the system, that result will give you the avenue to persue.

It's the extra load on your engine when AC compressor kicks on, and it draws engine rpm down. Your fuel injection system has what is called an "idle air control valve", that is supposed to overcome that and adjust idle up & down automatically as needed according to engine load conditions. I'd say it needs replacement, unfortunately it's a little more expensive than most & will run you about $165. Before you do, if you do, make sure all connections & any hoses running to it are in good shape no cracks, on tight & clean, as that can also cause part to malfunction.

Neither. You most likely have a leak in the system and lost some refrigerant. Take it to a shop that is licenced to work on A/C

Check the cooling fan on the radiator. Sounds like it isn't working.
