sure sounds like a battery / alternator issue , take it to an autozone or checkers , let them test the battery and charging system as a courtesy , and a second opinion . thanks.

If it is happening when you change the AC and Defroster Modes as Stated above, You have a Wire inside the Dash in this Location that has Shorted and is Grounding itselt to the Housing for the HVAC Controls. This could cause a fire. I would pull the HVAC Unit and try and Locate the Faulty wire Behind it.

You probably have way too much unburned fuel in your exhaust system (how's your mileage?) or possibly a failed oxygen sensor that is giving false information to the computer.

Hi. here are a few steps that will help you troubleshoot this fan issue you are experiencing.
Step1 Check for broken wires or loose connectors around the fan circuit. Inspect connectors at the fan motor, relay, sensor or heat sensitive switch, and the Electronic Control Module (ECM)--your car’s computer control system. Also, make sure to check for a possible blown fan fuse. These are common and overlooked troublesome spots that may cause a fan to fail. Step2 Run and bring the engine to warm temperature. With the engine running, use a voltage test light to check for power to the motor fan. Be extra careful and make sure to keep your hands and tools away from the belt, fan or any other engine moving parts. If voltage is reaching the fan motor, the test light should glow. Step3 Turn off the engine after you see the light glow. Apply direct voltage to the fan motor from your car battery using a pair of spare wires. If the fan fails to operate, replace the fan motor. If the motor operates, your problem is in the motor connector. Step4 Locate the heat-sensitive switch or heating sensor if the fan motor operates with direct voltage and the test light did not glow. You should find the sensor in the radiator, engine block, or thermostat housing. Step5 Measure the resistance across the heating sensor with the multimeter. With the engine at cool temperature (engine off), it should register infinite resistance; with the engine at warm temperature (engine off), you should read low resistance. If both readings state infinite resistance install a new heating sensor, that’s the cause of your failing fan. Step6 Check the action of the fan relay if the heating sensor is registering variable resistance. Your service manual should specify the power and ground wires according to color codes and the proper way to test it. If the fan relay fails the test replace it with a new one. Step7 Check the connections going to the ECM after you determine the fan relay is working properly. If you find broken wires or loose connectors, make the necessary repairs. If you suspect a defective ECM take your vehicle to a service shop for a computer analysis. In most cases, the ECM is rare to be the cause of a failing fan. The above steps should take you to the root cause of your problem and help you fix the cooler fan.
Please rate and god bless.

that is a wiring problem or corrosion in the socket. make sure the socket is clean. then test with a multi-meter while the left blinker is on, if you have voltage then it is the light, if no voltage is present, you will have to trace it back to fuse box, turn signal assembly.
