First post. A/C blows hot air and the compressor cycles on and off. I bypassed the low pressure switch, put a gauge on the low pressure sideand filled the system with freon. Hooked the switch back up, compressure runs fine now but no cool air. I did notice the low pressure line going into the condensor is cold but the high pressure line is warm/hot. Any ideas? The A/C hasn't work in a year or so. It's hot here in Florida!

Thanks in dvance

Evaporator core is usually the case in these trucks. Just replaced mine 2 weeks ago.

 

Did you replace it yourself? If so, was it difficult?

 

Did it myself. Not bad took about 4 hrs. There's a complete how-to in the DIY link at the top of the page

 

krs7272, looked all over for the link in DIY. Only one I found was for a Dakota and that one was intense. Could I bother you to post the link?

 

Think I found it.

Check the vacuum lines to the dash control.

 

Iwent into a more detailed explanation

 

But I'm not wasting another ten minutes

 

Also what kind of pressure readings are you getting after adding freon? Even when my core leaked like a stuck pig it would at least hold for a few maybe and hour.
