catdaddy300 Posted May 21, 2010 Report Share Posted May 21, 2010 I let my buddy barrow my truck and he heard the same thing but when the A/C is on i hear a whisleing sound and it is scary. The A/C has gotten less cold over the pass few days so i plan on putting more Freon in it but has this ever happend to one of you guys. well i think it is the A/C anyways Quote Link to comment Share on other sites More sharing options...

How often do you hear the clunk? You are probably hearing the AC Compressor clutch engaging.... Quote Link to comment Share on other sites More sharing options...
stg313 Posted May 22, 2010 Report Share Posted May 22, 2010 Does it sound anything like a slight belt slip? Check the belt and pulleys......... I just had to replace my AC belt Quote Link to comment Share on other sites More sharing options...

catdaddy300 Posted May 23, 2010 Author Report Share Posted May 23, 2010 ok what kind of freon do you guy recommend to at least get my A/C cold again Quote Link to comment Share on other sites More sharing options...
mbarnes Posted May 29, 2010 Report Share Posted May 29, 2010 theres only one kind youll be able to get your hands on r134. you can get cans at all auto parts stores or even walmart has it. ill tell you though that if your low on freon it had to have leaked out somewhere and the new freon will do the same.
