Fantastic testing and diagnosis you make it look easy and to most of us it isn’t. Bloody hell £600 for the motor 😩

[@mrautoservices7354]

Thanks Kevin 👍

All your videos show excellent diagnostic skill and rule out the common wiring and other faults!
The "simple" approach of "Blower motor doesn't work" fire parts cannon and replace blower motor didn't work!
Did the customer have to pay for the outrageously expensive motor AND a switch as well as the garage time and your diagnosis?

It's gonna be roasting tomorrow.
Nice find.

This fault was listed on some data sheet I have. And the AC pressure switch was the cause. ha ha. Jogged my memory. Had you asked me I could have told you. Had you known that is.
So what codes did you get...?
