generally you could remove a head and measure the bore with a micrometer.
then read specs on the vehicle and what it's original engines bore was.
make sure an engine was not swapped into the original engines place.
Check to see if you are getting power and ground to motor - if so and motor does not work- bad motor
Disconnect wires from motor and check to see if you have power and ground going to motor--if so motor is bad if not have to check wiring and switch to that motor
Check to see if you are getting power to the motor - if so bad motor -if not check fuse, switch, or resistor
Check to see if you are getting power to the wiper motor. If you are it is likely the FUSE, but if that's already been checked it SHOULD either be, the wiper motor or the switch, I would guess the motor.
Check to see if it is getting power - if so defective motor Run a "Hot" line to motor to see if it starts Check fuses Check sensor at rear of radiator
Check the fuse Check to see if you are getting power to the switch -if so see if you are getting power to the motor - if so probably a bad motor
First check for a blown fuse. Check to see if there is power at the motor. If there is power at the motor then the motor itself is bad.
See if power is getting to fan motor--connect a test light and turn on A/C or defroster--if getting power to motor. Then motor is bad. If not getting power to fan-- Check fuse Check relay See if power is getting to fan motor--connect a test light and turn on A/C or defroster--if getting power to motor. Then motor is bad. If not getting power to fan-- Check fuse Check relay
See if you are getting power to it - if so bad motor If not check fuse relay breaker Check to see if you are getting power and ground to switch
Blown blower motor fuse? Bad blower motor or resistor? Check to see if you are getting power to motor - if so motor is bad if not check fuse and/or resistor Bad switch?
check to see if your lowon freon
when motor stops, tap on motor and see if restarts. if it does replace motor. there is a bad spot on the armature. if not check the blower resister.
