air conditioner blows 100 deg air on max ac.

Do the AC lines under the hood get cold with the system turned on to max cool? Could be a bad orifice valve.

Thanks for responding so quickly. Yes, the AC lines are cool. I would assume a bad orifice tube would give me warm air but also an abnormal high head pressure. I am only getting a 150 psi head pressure.

I am measuring 100 deg. F at the register. It feels like there is only heat. There is no temperature control. I did not measure the back registers to see if the same condition exists.

thanks

By "there is no temperature control" I presume that you mean you have no control over the temperature. Remove the control panel assembly from the dash and follow the cable from the temperature control to the airbox. Make sure it is connected. Make sure it moves the actuator outside the airbox. Also, listen for the blend doors moving. Check all vacuum lines and wiring to the airbox and control panel.
