94 ranger A/C challenge
I have a ford Ranger 1994, The A/c would be cold upon starting and then blow hot air after 5 minutes or so. Later..the engine ran hot, so I added antifreeze..Now the A/c works fine.How are these related?

Buy a Haynes manual--it helps with Illustration 6-11 in Chapter 5 about AC troubleshooting. It will tell you everything to check. Especially which posts to check on the AC WOT relay. Very nice diagram....

The air conditioning condensor is a "mini radiator" used to cool off the warm freon after passing through the evaporator. It is situated directly in front of the engine radiator so the air flow can cool it off, as well as the engine radiator.
When the vehicle overheats, the heat from the engine radiator can transfer to the condensor and actually heat the freon up more, hence hot A/c.
Some cars will also shut off the A/C compressor if the engine reaches an overheat condition, once again resulting in warm air.
Hope this answers your question.
