1986 Jaguar XJS Blower motors.

Air Conditioning problem
1986 Jaguar XJS V12 Two Wheel Drive Automatic 50K miles

I have a 1986 Jaguar XJS, after placing it back on the road this spring I noticed that I was getting no air flow out of the vents.
The A/C works as when you start off down the road you can feel a little cool air coming through the vents.
I checked the fuses (all that I could find. There are many) replaced the A/C relay, but have not checked the voltage at the motors or the switch due to the nightmare of reaching them on this model.
I also found out that there are (2) blower motors and the odds of both of them going south at the same time are remote.
Any thoughts? The V12 puts out a lot of heat and in the summer. It's a nightmare!
Thank you for your input and thoughts,

Best
