SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

SOURCE: pressure on low & high side reads 110 psi and wont charge

Check the exspansion valve its part of the evaperator on that car for being clogged.

SOURCE: 1997 Chevy S10 A/C not cooling. Fan blows

sounds like the airbox doors are not working these are located behind the dash passengers side, a chiltons manual availible at most parts stores for around $25 will give you diagrams and steps to access this area if u need that help

SOURCE: 2005 Dodge Durango Front AC won't blow cold, back air works great

Did anyone find the answer for this?

SOURCE: 99 Toyota Tacoma a/c reads high pressure on low pressure side

Does the compressor run?
Low side could be high without a running compressor.

A running compressor?
The expansion valve itself is about $50 and bolts in.
You will have to remove the 134a gas before installing a replacement expansion valve and vacuum the system before recharging.
