My left signal light starts slow for about 4/5 blinks then goes double the speed (the front signal light doesnt blink) Also the indicator on the dash stays on solid weather or not the signal is on. My left headlight is also extremely dim, and new bulbs were put in about 3 months ago. My wiper blades wont move. When i turn the wipers on, they move about an inch and then stop moving. I plan on checking the relays for wiper blades but I don't know about the blinker. All these problems started about 2 weeks ago.

OK great work.



For the battery light - We need to know what the battery voltage is at the battery. It should be about 12 1/2 with engine off and about 14 1/2 with the engine running. If very high, like 18 volts, it is overcharging and will turn the light on too. Check fuse #10, red, 10 amp, in the engine compartment fuse panel first. Report findings.



PS. Please rate highly if this helps resolve your problems, thanks.

The PCM (engine computer) controls your alternator output. It will not be the PCM, never is. Here's info from the shop manual:



The charging system voltage is controlled by the powertrain control module (PCM). The generator charges the battery and at the same time it supplies all the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to battery temperature by using a signal from the intake air temperature (IAT) sensor. This means that the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.

The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged the system is able to increase the idle speed.

To minimize the engine drag when starting the engine, the PCM controls the generator. The generator does not produce any output until the engine has started. The PCM then progressively increases the output of the generator.

The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key - on engine off and stall conditions.

We'll go from there.

I think your alternator is OK and the internal voltage regulator as well. I would not change it yet.



this sounds like a PCM control wiring issue. Your voltages are all good.



Need to know when the light comes on. And when it's on, what is the voltage reading. The light will come if it's overcharging too. And that is usually a corroded wire between the battery and the alternator (heavy wire).



66% of alternators replaced are not defective. I think your alternator is OK and the internal voltage regulator as well. I would not change it yet.
