A/C air

The left side vent, on the center panel, blows barely cool air, and the right side vent blows cold air, when the A/C is operating. Any ideas out there

is the temperature set to a low degree on the driver side.
If you override auto and set the fan high on driver side does it blow cool air?

Thanks for responding. I found a site that said that the condition I had was caused by low freon. I have a set of 134a gauges so I checked the pressure, it was showing about 30#, so I gradually added freon and checked the outlet temperature. I stopped adding freon at 35# as both sides had an outlet temp of 40 deg. The site I read this info on was an E46 site, different car but end results were the same. Thanks!

Where is the low-side valve on your car? I haven't been able to find it on mine.

As you look at your engine, look down the front left side and you'll see it tucked away..

Use a gas/sealant product.

Protect your arms though as it gets hot down there lol

Have it cleaned then..

When running on cold, moisture builds up on the coils and these cause all manner of unpleasant bacteria so it's best to have the a/c serviced at that point..

To avoid it (or reduce the time it takes to stink), try switching your a/c to hot 10 mins before you park up the vehicle to dry the coils and thus prevent the build up of bacteria.
