THANKS FOR YOUR ANSWER. IT WAS A TOUGH QUESTION

Broke down and took it to dealer. Erratic action was due to temp control computer chip. $325 but does work now.

Eariler question never answered.

Air conditioner compressor cycles as though everything is OK. However the blower comes on for a minute the quits and after awhile it will come on again and may stay on for awhile. But will cut on and off regardless of temp in side. Thanks. Rdjrich

Still no answer to solve this problem. Will another donation help to solve this query?

Sorry Rich,

IF we can't help, I believe they will offer your money back. But let me give it a shot.

We have a caddy guy here, but haven't seen him online most recently. He typically handles them.

Will the blower stop on every speed?

IF you know where the blower is, try a tap test to see if it starts back up or stops.

IF the blower is not working and not responding to a tap test. REmove the harness and check for power to the harness. Also can run power directly to the motor with the harness off. IF there is power and no blower action, it need a blower.

This m, ay be a intermittant problem due to a connection or wire issue as well. Somtimes wiggling the wires that are accessible can flush out a problem or a continuity check is needed.

That is where I would start.
