Have 03 spectra with codes po650, poo30 and po134. charged ac clutch is engaged but blowing hot air. is all this related


To clarify, none of this has anything to do with your a/c.
Code 650 is for a problem with the check engine light circuit.
Code 30 and 134 involve the heater circuit for the O2 sensor in front of the catalytic converter. The O2 sensors have a heater that allows the sensors to start working quickly after you start the engine. The sensor and the heater circuit would need to be tested.
The O2 sensors have nothing to do with your car heater or A/C.

It does sound like it is an electrical problem, possibly in a harness (damaged) or the ECM had major issues that a reflash could not overcome.

You should replace the O2 sensor that is in the exhaust manifold or exhaust pipe just off the engine and before the catalytic converter.
