My A/C worked great the day I drove it to stress free auto care in Concord CA to have a lower mileage engine installed. It took them 3 weeks to complete the process. When I picked up the car two days ago the A/C didn't work. Before I left, I test drove and let them know A/C doesn't work, it did when I brought in. They then added freon which I had recharged the freon before I took it there. They wanted to charge me $205.00 to diagnose the air conditioner not working. Which wasn't right because it worked when I brought it there and after engine Install it didn't work. He then stated to me there was no way anything that they could have done would. What a because the air conditioner not to work? Which is bull dookie because anything could happen on an engine install. Do you have any suggestions at this point when it blows hot air? I don't want to take it to them to diagnose because they obviously wouldn't admit it if they did make a mistake. Considering calling the bureau of automotive repair.

Hi,

When the engine was removed, nearly everything related to the A/C was moved around. When I remove one of these, it is done through the bottom of the vehicle with the transmission attached. I suspect they did the same. So, the A/C compressor would have been removed from the engine (I would think) and placed in a location to prevent damage. If they weren't careful, it may have damaged a hose or other component and it lost freon.

When they added Freon, did the compressor start engaging? If not, was the wiring to the compressor inspected as well as fuses/relays?

Let me know.
