The relays for the blower are under the hood, near the top of
the firewall on the passengers side. You will need to remove the
plastic "fuse cover" to access them below the fuses. Replace them
one at a time to see if this fixes the problem. If the blower is
running intermetantly, then you may find you have to replace the
blower motor (I needed to do this on my car $45). In order to do
this you'll have to remove a bracket and several other lines in
front of the blower motor to get enough clearance. If it works only
at certain fan speeds then also check the blower resister located
under the relays.

I believe there isn't one, i have a '91 LeSabre and it doesnt

like you have a problem with your headlight staying on all the
time. If that's the problem then i cant help you.

Why does the right turn single on a 1985 Buick lesabre limited stay on on the right side?
If you mean it stays on and does not blink then check the other
turn signal bulbs on the right side front/back.
If it blinks but does not turn off when you make a turn then the
problem is in the steering column canceler.
