Question about 1991 Toyota Camry
Check the fuse or the circuit breaker.?Remove wires at the blower motor.One will be the ground wire,black,in color?? the other will be the hot.If there is only one then the motor is grounded by its mounting. Check wiring diagram.for colors or use an inline fuse 20 amps. in the power test lead Run a ground wire to the other. A premade set of test leads are very helpful.This will test the motor.The fuse may blow if the leads are reversed or the motor is shorted,or draws too much current.If motor tests ok,repair the open.Test the switch and the high speed relay,then the resistor packl All with finction of the blower switch.No slow speeds,bad resistor pack or switch,check resistor(visually),no high speed with switch?Bad highspeed relay. A wiring diagram will be of help,in checking points in the circuit where the color code is used.Without a diagram is a guessing game and takes more time.
