Isuzu Repair: 1995 Isuzu Rodeo A/C + Heater, blower motor resistor, isuzu rodeo

Question
QUESTION: My A/C and Heater just stopped working in the middle of the day. I checked the fuses and they look fine. What else should I check? Also, my fuse box has a 10A fuse for a TCM and a 10A fuse for a A/T Lock; what is a TCM and a A/T Lock? Thanks for your help.

ANSWER: Well Does it blow hot air or does it not blow at all? The a/t lock is your automatic transmission lock and if I am not wrong the T.C.M. is  the Transission Control Module Mike. The a/c needs a combination of things to run properly. Like a delicate blend of freon and oil, plus the a/c compressor, condensor, filter/dryer, expansion valve/orifice tube, and the evaporator. If even one of these is not functioning correctly the whole system will suffer. I would need some more info on what it is doing or not doing to better help you please. Thank you for your patience as well.

QUESTION: Daniel,
 Sorry it took so long to reply. It is not blowing anything. Heat, air, nothing. I do not even hear the motor. Thanks for your help.

Answer
Well I would check the blower motor resistor that is by the blower motor behind the glove-box if I am not mistaken Mike. Also check the fuses/relay and the connections that go to the motor as awell as the motor itself to see if it is getting 12 volts to and from it.
