Have a problem with a 2003 Pontiac Bonn. The engine will not rotate when turning the key. I have NO interior lights, windshield wipers,blinkers heater fan, radio or inst. cluster lights. The inst. cluster will light up with the headlights on. I have replaced the ign. switch and the problem still exists. Problem seemed to happen when the car battery was dead and someone decided it was a good idea to use a cig lighter charger system to charge/start the car. Please help!

Re: Have a problem with a 2003 Pontiac Bonn. The engine...
You could start by checking the maxi fuses that feed the ignition switch. If you don't have power to the fuses feeding the ignition switch, the problem would be between there and the battery. The best tools for finding this type of problem is for me, is a wiring diagram and a test light. A test light is $5 at an auto parts store and you can copy your wiring diagram for ten cents a page at your local library...
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

First you need a wiring diagram, free at http://www.bbbind.com/free_tsb.html Then you need a DVOM - digital volt ohm meter to test the circuit . Then if your not familiar with automotive electrical systems testing ,go on youtube an check out Electric Testing Techniques You Need to Know Also having a factory diagnostic trouble shooting chart would also be usefull . You could just start replacing parts , you mite get lucky . The wiper motor is a high fail part , so is the switch ..You could find the fuse is blown ! But fuse's don't usually blow without a reason . Short to ground , low resistance . ( high current flow) Also knowing how they work and what all is involved in making them work.
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor module
• Windshield wiper motor
• Windshield washer pump motor
• FRT/WPR/WSHR 25A fuse
Wiper/Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all of the low speed modes. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits and the wiper motor high speed circuit.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.
Don't the wipers work in any mode ?
Did you review the Wiper/Washer System description and operation and perform the necessary inspections?
YES - Go to Step 2
NO - Go to Symptoms - Wiper/Washer Systems
Turn ON the ignition , with the engine OFF.
Operate the windshield wiper/washer switch through all the switch positions.
Does the windshield wiper/washer system operate normally?
YES - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
NO - Go to Step 3
Turn OFF the ignition.
Disconnect the harness connector of the windshield wiper motor.
Turn the ignition ON, with the engine OFF.
Connect a test lamp from the accessory voltage circuit of the windshield wiper motor to a good ground.
Does the test lamp illuminate?
YES - Go to Step 4
NO - Go to Step 13
Connect a test lamp from the accessory voltage circuit to the ground circuit of the windshield wiper motor.
Does the test lamp illuminate?
YES - Go to Step 5
NO - Go to Step 14
Connect a test lamp from the signal 2 circuit of the windshield wiper switch to a good ground.
Press the windshield washer switch.
Does the test lamp illuminate?
YES - Go to Step 11
NO - Go to Step 6
Let me know if you make it this far and i will send rest of diagnostic's
2000 Pontiac sunfire has an interesting issue; the wires corrode in the wiring harness. I'm not sure about just turn signals, it is usually multiple issues. Maybe your driving lights quit too? and maybe you windshield wipers? Start out by running a ground wire from the engine to the firewall; maybe attach (to experiment ) a ground wire to one of the mounting bolts on your windshield wiper motor. I'm guessing the ground is gone.
I am having the same issue with my 2003 bonneville. Changed out the control switch, no difference. Changed out wiper motor, still no difference. Seems that the problem may be on the wire for the delay. There is a constand 2.5 voltage when the switch is in the off position, cause the wipers to run intermitently. The wipers will run more often if you rev the car engine and increase the trace voltage. A wire is going to be added to bypass the bad wire in the harness. Crossing my fingers, hope this works.
There is two place that you can check which would cause this problem. (1) the switch it self and the other is the (2) circuit board on the wiper motor. It's common for the solder on the circuit board where the wire harness clips on the wiper motor to crack and needs to be re soldered. You can buy the replacement at Auto Zone or you can re solder it your self to safe you the $15.00 for the board. If you give it a light tap and the wipers stop, then it's the circuit board. If it keeps working, then it's the switch on the steering column and you can get that at Auto Zone also and they will have the step by step instructions for you to get the hob done with common tools. Good luck and keep me posted.
