A/C Not Always Cooling
 

Hello every1 , I got Isuzu Trooper 1999 . its problem is : when i switch on
the engine , the A/C works , but hot air comes out , Unless when i press the
gas on , after some time it works , or when i am on a high way, but as soon
as i stop for a trafic light , it become humid , and hot... So i changed the
Compreser . but still the same probelm... So...Any idea , and 1 more thing ,
does the ECT Switch or A/C thermo switch got anything to do with that???? My
regrads

A/C Not Always Cooling
 

BTW : I just checked the Condenser fan , and da cooling fan , and both r
working when da AC is turned on..
