B1242 | Air Flow Recirculation Door Driver Circuit Failure | |
This is more common than you would like. The actuator for the fresh air and recirculate doors has failed, and it broke a plastic rod connecting the doors when it failed. It's annoying, but it's not causing your problem.
B1947 | Climate Control A/C Post Evaporator Sensor Circuit Short to Ground |
This is what is keeping the AC compressor off. It could be the wiring, but it is probably the sensor itself. Fortunately, it is only $30 or so. If it is the sensor, you can unplug it, and the AC should go back to working. (Without the sensor, it can freeze up at times, so you do want to replace it.)
This may help you find it. It's under the dash, driver's side toward the middle, part way up.

I have searched the web over and cannot figure out what to do to fix this code.I had ice cold a/c this morning while driving home from church. Then after the car being parked for a couple hours I turn the a/c on and notice that the ac clutch is not engaging and I have hot air out of both sides...
