At the end of the summer last I had the ac evaporator replaced along with the condenser and part of the refrigerant line. The air would stop coming out on acceleration and this year a little comes out of the defrost, no matter where I move the vent selector.
Aside of something broken-is there something they could have screwed up when they replaced the evaporator-something they left out-somewhere I should start the process of elimination.


Thank you for any help,


Bob H.-hot and tired!
