My car listed above is a hybrid, I changed my battery (12 volt) after that i had issue in the compressor .
when i switch on the A/C only the internal blower working with hot air. i removed the negative cable and wait for 10 minutes to reset the computer after that i drove my car for 124 miles but still same issue. also i checked all fuses and was okay and i checked the electricity from compressor side it is okay. It is full of Freon.
Please help. i do not know if there is any special fuse i should check or the Evap sensor has problem.

Hi,

Did this just happen after you disconnected the battery? There isn't a relearn or anything involved, so we need to do some checking.

First, I attached a couple pics below. The first one shows a fuse that powers the AC compressor module. Check to make sure it is good. Also, make sure there is power to the fuse.

Next, I attached a pic that is from the wiring schematic related to the module I mentioned. I highlighted a couple wires that are high speed CAN. What I recommend is to have the vehicles CAN bus system be scanned. CAN stands for computer area network. The modules are all tied together. If you scan it, it should indicate where there is a problem.

Here is a video that shows how it's done:

Let me know about the fuse and if the scan is something you can do or have done.

Take care,
Joe

Have you checked for power at the AC compressor clutch?
