before tearing into the dash to find this relay.
I would test the blower motor when it is non-functional.
It could be bad brushes as it is just a DC motor.
Try "Foonzie-ian" it
When it is in a non operating state - turn it to high speed
(#4) and tap
on the motor (under the glove box).
If the motors starts, replace the blower motor.
You could obtain a cig lighter adapter with cord.
The motor has two wires running into it,
one blue the other green/white.
Connect the wires from the cig lighter cord (ig. key must be in the run position) to the wires to the motor.
Polarity is not important as this is just a test.
If the motor runs then do as Gloyale says,
pull the dash panel that is above your knees when driving.
Lie on your back or use a mirror to look up above and beside the st. col. Four relays in tandum.
Relays are round canisters about the dia. of a quarter
and about 1" in height.
relay wire colors
note fuses #
1,2, and 12 are used to control the relay/blower
Hope this helps.

They are very hard to see,
dim light is not the answer here Dave.
The ECU is in the way and a mess of wiring.
My feeble old mind and body find it much EZ'r to prove
it is the trouble
before looking for more.
Should you inadvertently knacker another connector
loose in your search -
then come to find a nest of mice jammed the blower motor.
Sir you will not be the first to have this happen.
Good luck and use a good light.
You will need both,
as I doubt this helps,
sorry but I tried.
