I have a 2004 chev silverado. The a/c stopped cooling. I checked the charge which reads ok- the dryer will not get cold- the line with the expansion valve is hot till you get to the valve,(the long one with the screen in it in the line) then after that point it turns cold. The dryer is hot though. My coil in front of the radiator has been bent bad somehow- I dont know how but it is- and the capilary tubes runniing crossways in it are smashed some- no leaks tho. My compressor is kicking in too. I replaced the dryer, recharged it- still the dryer is hot and the a/c barely cools. HELP! can it be the coil in front of the radiator doing this?
