I guy at work needs to change the heater motor in the sons 88 YJ.
I was asked what is involved and I don't know. We looked at the CT manual and it did not say anything useful.
So I'm putting out to the experts.

I'm afraid it's not that simple , the heater needs to come out from under the dash.
So , drain cooling system , carefully remove heater hoses , locate all the 1/4" fasteners inside the engine compartment and remove them I think there's four or five of them , some in hidden locations , wrestle the heater back far enough to get at the fasteners which hold the motor/fan in , carefully remove fan from the old heater motor and install on new motor , reverse the procedure to put it all back together , paying attention to the defroster ducts n' stuff so it all goes back in as it was before messing with it.
A pain in the butt to do and there's no easy way to do it , as with most vehicles when dealing with heater motors / heater cores and dissassembly of the dash.
If you want the heater right out of the vehicle , the control cables need to be disconnected , be careful , the control is fragile and easily broken.
