Had my flywheel replaced by a garage. Got car back and several problems with Climate control.#1 - when AC is on blows cold air but not through dash....#2 when I try to put on heater no heat blowing just cabin air...#3 No clicking sound from modular actuator however getting an occasional chirp from engine compartment when AC running....problem codes are B1340/B1343/B1344...Checked fuses all are good. going to take back to shop where work was done but would like to be able to know what problem could be BEFORE I take it in....Your knowledge is my ability to hold mechanic liable...Thanks

 

welcome, year and model? air flow- vacuum leak. Removing transmission should not cause low "Freon". poor connection at connector or ground.
