Help!! Like to know what all is involved in replacing a evaporator coil on a 96 Chevy P.U.2500. Just had the motor replaced by a Chevy dealership with a 3 year 100,000 mile warranty. They also replaced most of every thing on the top side, dist. water pump,manifold,injectors,wires,bla, bla ,bla. I even replaced the clutch fan and radiator new battery and alternator( new) not rebuilt. Any how I took the truck in to have that 350 replaced and with a working A/C for years. They said my A/C hose that runs in front of the "carb" and then behind it was leaking. so they replaced it and recharged my system. Well now my evaporator coil is leaking out all the freon and they say that they had nothing to do with it. The dealership recharged the system and added a die in the system...well when they showed were the leak was with a black light and yellow glasses it was dripping from the drip system from the AC evap coil. After ticking off the mechanic and the salesman ,I am left replacing what is broke.Could they have recharged my system and blew out the Evap. coil? I am over $7,000.00 into this motor. I should have street racer at that price . instead I have a very reliable heavy duty 3/4 ton Chevy W/O A/C!!!
