I have a 1995 F150 5 speed. I need help locating the "low pressure" intake valve to refill my A/C. There was no info in the owners manual
Thanks

 

I believe, the LOW PRessure schrader valve is mounted on the side of the DRYER/ACCUMULATOR. It may be covered by a plastic housing around the DRYER/RECEIVER. Give that a PEEK-SEE.

 

Usually the "low side port" is located on the larger of the two A/C hoses/lines coming from the A/C compressor. It can also be located on the accumulator/dryer as previously stated by Common Sense. Vehicles using the new 134 refrigerant have two different size fittings intentionally so you can't get the fittings on incorrectly. Let us know if you were satisfied with the answers and if they helped you. Thanks, hanky

 

My ford F150 guit blowing cold aircondtioned air out the dash vents and the air only comes out the defrost vents still cold but not blowing out where it should

 

Typical senario for a vacuum leak in the vent system (most common issue). You will need to check for a vacuum leak under the dash for a loose/cracked/broken vacuum line. Also check the control head wher the vacuum line plug into. Check the vacuum line under the hood that feeds from the vacuum cannister that maintains vacuum when the engine is under load. You could also have a stuck/broken vent door that is stuck in the defrost mode.
