Heater
blower not working?
Richard Wood posted a note on the V8 Bulletin Board seeking
help with a heater blower that would not work. An enthusiast
in Germany spotted a possible solution which solved the problem.
(Dec 10)
After
owning my RV8 for about five months I realised that the heater
blower wasn't just very quiet and not good at moving warm air
into the car but actually didn't work! Yes I know, but once
you are moving there is a good flow of ram air from the scoop
just in-front of the windscreen!
Anyway as I had booked onto the Wigton Motor Cub Christmas Cracker
Run due to be held the following weekend, the exceptionally
cold weather at the time was a real concern. We had -3C during
the day and temperatures were dropping daily, so it seemed a
good idea to replace the blower motor if only to save the marriage.
So I sourced a new part from Clive Wheatley.
It arrived
promptly and I set about fitting it which involved adapting
the housing to fit. First I removed the old unit and popped
a label on the two motor wires (red circles around position)
and removed the four (fairly accessible) screws - three of them
are shown with yellow circles around them in the photo. They
hold the motor in and once removed the unit comes away very
easily.
The
new motor needs to be fitted into the external casing of the
original unit. The contacts for the wires are in a slightly
different position, but nothing that a torch and a Dremel (or
similar) multitool cannot resolve. The picture below shows the
original (yellow) and the new (red) wire positions.

On
completing the replacement of the blower motor I switched on
- and nothing happened! I could only think when the original
motor failed it took the fuse with it? Although I have a set
of RV8 manuals on an RV8 Technical Information CD supplied by
Brown & Gammons, I was seriously short on time because of
work commitments. I tested the power to the blower motor and
there was nothing there so I posted a note on the V8BB to see
if anyone had any tips or knew which fuse is the one for the
blower and where the fuse is?
Peter
Garton responded saying "if you look at the fuse box with
the two centre rows of a total of 26 odd small fuses in it,
it is number 14, which is the bottom left fuse. The RV8 Owners
Handbook describes how to remove a fuse by using special tweezers
- "press the removal tweezers on the head of the fuse and
pull".

6 of the RV8 Repair Manual AKM7153ENG and Fuses pages 111 &
112 in the RV8 Owners Handbook AKM7144ENG.
Richard
replied "fuse number 14 it was and now the blower is working
and fully refitted. Not sure what the weather is like in Germany
but we have snow on the ground in Lancashire and I hear it is
worse in Cumbria, however the rally has two routes and at least
we'll be toasty now we can hear and feel the heater is blowing
warmth into the car. Thanks again for your help on this and
other posts".
Postscript:
the day before the Christmas Cracker Run there was a further
heavy fall of snow and the run was postponed until January 2011.
