I need some help, I have a 2004 TB that has numerous issues;
First the battery light stays on even without the key in the ignition.
Second the low fuel light will flicker even when I have a full tank.
Third The idle is rough at times especially when the A/C is on.
Fourth my voltage guage is not accurate. Neither is my temp it registers on the cool side.

Now what I have down to correct the problems.
Replaced Battery & alternator.
Checked all the fuses.
Ignition switch has been replaced @ 34,000 miles. ([email protected],000).

The new alternator has my temp and voltage guage issues solved I think.

Also I have noticed that these issues come about when there is high humidty, or rain. Even if I am not driving. Any help please!!!!

First of all Welcome.

First the battery light stays on even without the key in the ignition.
-Can't help you there..

Second the low fuel light will flicker even when I have a full tank.
-Maybe a bad fuel level sensor in the tank.

Third The idle is rough at times especially when the A/C is on.
-Have you cleaned your Throttle Body lately?

Fourth my voltage guage is not accurate. Neither is my temp it registers on the cool side.
-You might have a couple of stepper motors going out on your instrument cluster. A simple replacement of the stepper motors is a solution.

Those are the most common fixes for what you are describing. I am sure others will chime in as well..

Please fill out your user information so we can get to know you and your vehicle. It will help when people are making diagnosies.
