89-xj40- Daimler blowers-not-working?
I have read almost every thing I could find out related to the mal-functionning of the blowers.
Thanks for these useful posts;
I am confronted to the following issue: when setting the blowers at high speed, then the fuse A2 (Right box) is immediately fusing; the fuse on the left side is Not fusing and I can hear the motors (low/ medium/ high speed).
My question: where to search for a faulty component: right blower motor? or electrical circuit (from where to where?).
As the car has other electrical issues - all located on the right side of her -
I would like to understand what could be the common cause for these "right sided" issues.
Any ideas?

The blowers- I suggest but have "No" idea if there even Is one- Is there a bad resistor to the right side motor?
The window switch, I had no response at one back door and intermittent at other back door but the driver switch would work. Replaced both switches and its fine now. I tried taking the switches apart to clean contacts but had no success.
The SLS is something I have no experience with. Cant help there. Good Luck

I have investigated the Right blower.
Found that one of the relay (inside left) is having significant black traces (carbon?) around the contacts.
found also that the motor was not rotating.
I finally decided to make the motor running again, but without extracting the full blower from the car.
I opened a "door" in the black box and then was able to "degrip" its rotor, first with hand and then by switching the motor to an external battery.
The motor started to run after a few gentle schocks on it while linked to the battery.
And it started. I let it run for an hour+ and tested that it was able to start again without the need to hurt it.
Put some electric spay on the external part of the motor axle, and also on the rotor itself (very small quantities)
The next steps will be to transfer the 2 relays outside the blower and the close the "door" reusing the original parts plus some glue to make it airtight.
At this stage one certainty the motor runs.
I will then change the damaged relay.
attachment : the opened carter of the blower

Final stage of the right blower recovery:
all the electrical wires and relays are now located outside the carter:
an electronic card (what is its role?) is plugged outside the plexiglass and the 2 relays are now located (not attached) on the left top of the blower; they can be accessible through the little trap inside the glove box
The "door" opened in the original carter is now closed with a "plexiglas" (one can see the motor from outside).
The final esthetical result is not brillant because of the difficulty to work in this narrow space.
