Yes I have a multi meter. I have done the ambient air sensor paper test and that was ok. Checked all the wiring for any loose or bare wiring found none. Thanks for your response

Ran the test and no codes but the blower still runs on high but when I hit the off button the blower motor sounds like it gets faster. Would the blower motor relay have anything to do with it?

No the blower motor comes on when the key is in the on position and when it is started and does not shut off till I turn off the car or pull the fuse.

Also got a code 36 which I think is the communication problem with the ATC head how do you repair that. Is that a problem with the BCM to the ATC or does that have something to do with the Ignition switch module not talking to the BCM or the ATC? Also wherer are the grounds for the blower motor, resistor and the ATC Control.

I was reading the trouble tree you sent and I need the Fig so I know where the pin locations are so I can preform the required test. Also The blower motor is the only problem I am having everything else on the ATC head works. Thanks for all your help.
