You'll have to climb under the dash and get to the blower motor. When you see the wires coming out of the blower motor, trace back about 8 inches to where those wire go and that with be the the relay (Resistor)
THE RESISTOR BLOCK is not equal to Relay. do you need a schemetic, to do this? Blower and resistor are on right side dash , USA cars, LHD. my guess, is this a , my blower dead on high , where is relay question? like most here. ??? the cab heater blower RELAY (im on line FSM now ) is marked HTR, and is located in the engine by box, 1 of 3 or more if ABS car the box is called EB-RB #1 left, (not JB2) and has a bank of relays, Fan 2, fan3 and HTR, (bingo) there it is, and is marked if you look carefully. left means , driver seating in car. i have the schmatic now, want it?
small, ask for large if serious, can tell you how it all works or better , real Diagnosis with any voltmeter made. ask.
as you can see, it can be lots of things, bad. a voltmeter finds it in minutes. no gussing. the relay, is on the left. there is a 50amp fuse driving it. the RISISTOR CAN NOT cause blower to fail on HIGH, why not post the symptoms>?

Why not post symtoms? is cab heater blower dead on HIGH??????
there are 5 fuses, just related to heat.
the blower relay is in the engine bay box 1 , far end marked HTR.
on high the relay coil 1 and blower pin 1 are grounded
the relay closes, if and only if the 10 amp heater fuse is good.
the relay then outputs 12v to blower in 2 and the motor RUNS.
that is it.
alldata.com read there.
or buy FSM for full facts. and schematics.
