Try to by-pass the relay for now....
Leave the relay out...unplug the lead to the blower,
run a new # 10 wire to it and to a temporary switch,then to the battery.
or #10 wire to the blower and a alligator clip to the battery.
You'll have to connect it and disconnect each time....but it's better than
And yes I know this is not a proper fix,but it should work in a pinch.
Actually, I had considered that option. My idea was simpler, though, as I
could "theoretically" just run the wire through a rheostat and back, because
if I'm not mistaken, it should be getting power as long as the key is on
anyway....of course, I could be wrong about that, too...haven't gotten under
there since the last time I replaced the relays a few years back.
My idea would at least bypass the need to disconnect/reconnect every time
I jumped into the car...but only if it DOES get power with the key on, and
of course, only if the switch I use has an "off" position and doesn't allow
any current through when in that position.
All I need to do IF that theory is correct is to find out what type of
rheostat to use...wattage, amperage...voltage is obviously 12 volt, of
I only said to run a separate lead so it doesn't back feed into the system,
since it is all electronically controlled.( Just like a Caddy,automatic fan
That way nothing could get damaged in the system until it is repair
best of luck..................Stan
