Help guys

My driver's side air is cool but passenger side is blowing warm air.
My dual air control is off. Same temp on both sides but passenger side is still blowing out warm air.

Anyone know what is going on?


Also, I think i'm running low on freon because my cool air is not as cold as it used to be.
is this the low pressure valve to refill my freon?

Low pressure will have a blue cap on it...industry standard last time I checked. Plus, only the low pressure side will accept one of those OTC freon recharging kits.

 

I have the same problem with my is250 07 i just buy it and found this problem can you please help me thx
