when i turn on ac it sounds like the heat flapper opens and then the heat turns on
ac was blowing cold then when I put truck in gear I hear the flapper switch over and then the heat comes on . a/c is fully charged
Is the a/c compressor running? If it is, then the a/c is probably ok. The problem is probaby in the mixture door actuator (electrical driven gear) if you have one or the blend door itself. Is the air coming out HOT (like having the heat on) or tempid like outside air?
Yes how do I fix it
Blows ac for a minute then I hear a thump then blows hot
