sorry for my typo. thanks for catching it.
I do not have a check engine light.
As for the fuse 15. I went under the steering wheel and checked every single fuse to see if any of them were blown... every single of them were still good. when i went under, i thought it was weird to find some of the fuse had a larger amperage than the required on the back of the handle.
Haha, no problem man, I was just messing with you.
The larger fuses would not cause your issues, but you should replace them as soon as possible with the correct amperage fuses to avoid an electrical fire. Fuses are inexpensive, I just bought a 150 count variety pack with test light and fuse puller included for $8.
Perform this test:
Use a voltmeter to read battery voltage at the following three times:
With the car off
With the car running and all accessories turned off
With the car running, A/C and all accessories, headlights, etc. turned on
Post your results.
Also check that the belt to the alternator is tight and not glazed or frayed.
