I just purchased an 97 s10 extended cab, the heater and A/C was working fine when I got it and two days later nothing works. I changed the heater & A/C controller inside the truck thinking that was the problem, but still nothing. The A/C won't even engage, I'm depressed wright now, HELP.

HI: Is the blower motor not working? If not, the place I would start is by checking the fuse. If it's good, move to the motor and check for power. If there is power, make sure the motor has a good ground and if it still doesn't work, replace the motor. If no power, move to the blower motor resister.

Let me know what you find.

Joe I followed your advise and it turned out the blower motor was dead, went to auto parts store and got a new one, I broke the fan trying to install it, used to old fan and it works now. I may have to take it out again becaues its off balance, but it works. Thanks for your help Joe.
