2000 FRC.

So I've searched, and tried what I believe is all the "fixes" i've read on here, hoping to hear something new.

so far I have:
reset the HVAC multiple times through the DIC.
pulled the HVAC fuse in the pass floor fuse box and waited for a while before plugging it back in.
replaced the drivers side blend actuator with a new one.

so far no change.

the air coming out of the drivers vents definitely range from hot to cool, just never "cold", which the passenger side vents easily do.

the driver's side vents blow at a temperature roughly equivalent to the passenger's side with the dual zone pass side set to the warmest setting while I set the driver's side to as cold as possible.


What am I missing? what else can I troubleshoot?

Maybe the system needs recharged..just an idea

I am seeing posts mention adding freon fixed similar issues.
I'm still not sure why the pass side would blow so cold if it were low, since the low pressure sensor should catch and shut off the compressor, but I will check that this weekend.
Thanks

It is a C5 known issue when refrigerant is a little low.

Take a look at this post. It has a chart that might be helpful to you.

if the freon is low you have a leak.....it doesn't just get low.

look near your schrader valves and all along the hard lines for signs of a leak....black greasy film on the lines....if you are lucky its a leaky schrader valve....easy fix
