1. Blown Fuse: Check the fuse box for a blown fuse that is responsible for the rear wiper. Check the fuse diagram in the owner's manual to identify the correct fuse.
2. Faulty Wiper Motor: The rear wiper motor may have failed. Try activating the rear wiper switch to see if the motor is making any noise. If you do not hear any noise, the motor may need to be replaced.
3. Bad Switch: Check if the rear wiper switch is functioning properly. Try activating the switch multiple times to see if the wipers start working. If the wipers do not respond to the switch, it may need to be replaced.
4. Wiring Issue: There may be a wiring problem between the wiper switch, the wiper motor, and the fuse box. Check the wiring harness for any loose connections or damaged wires.
Now, let's troubleshoot the front wiper spray washer:
1. Low Washer Fluid: Check the washer fluid reservoir and ensure it has enough fluid. If the reservoir is empty or low, fill it up with an appropriate washer fluid.
2. Clogged Nozzles: The washer nozzles may be clogged with dirt or debris. Try cleaning the nozzles with a small needle or compressed air to remove any obstructions.
3. Faulty Washer Pump: The washer pump may have failed. Check if the pump is making any noise when you activate the washer switch. If you don't hear any noise, the pump may need to be replaced.
4. Blocked Hoses: The washer hoses may be blocked or kinked, preventing the fluid from reaching the nozzles. Check the hoses for any obstructions or damage.
5. Electrical Problem: There may be an electrical problem related to the washer switch, pump, or wiring. Check the wiring connections and relays involved in the washer system.
If you're not comfortable performing these checks and repairs, it's best to consult with a qualified mechanic or an authorized Isuzu service center for assistance.
