04 sienna A/C

[sub0]

My 2004 Sienna the A/C is not very cold. I bring to the dealer to check before and they say there is no problem at all.

Yesterday the outside temp. is around 17 degree C and I turn the Air Condition to max and re-cycle the air and driving for 10 -15 mins. The air just cool not cold. So I do another testing.

I park my Van inside the garage and let it run...Humm the Air Vent in the middle the left side (driver side) is cool but I feel some warm air but the right side the front pass. side is pretty cold.

I wonder is that all Van are like that or is just mine ?


P.s Last year summer the outside temp is 28 - 30 degree C and I am on the highway doing 110 km/hr with A/C on over an hr. I just feel the air is cool not cold at all.

Any idea ! Should I bring to other A/C shop to check ?

On max cold the air coming out of center vents should be 40-45deg F depending on humidity in air. My guess is you have a small leak and freon is low.
