Have you checked the computer for trouble codes ?

bad or loose connections including battery terminals faulty voltage regulator

You need to pull the pressure sensor and install a manual test gage, (borrow from Autozone or other chain part store) that is the only way to verify the engine is not loosing oil pressure.

There is a relay which is typically plugged into the fuse panel. This relay is what makes the noise when the signals are on. They do go bad.

The first thing you need to do here is have the computer control system scanned for fault codes and an have a engine running test done to see what is going on in the automatic idle speed control system.

Yup! All those are right. REPLACE BOTH TAIL LIGHT ASSEMBLIES. (N.A.P.A. OEM Parts Only)...Easy (a little removal of the tail lenses...They plug right in. "Plug & Play!"

Hello , do you have amber colored turn lenses or red? I ask this because maybe the bulbs are not dual filament type in the brake light socket. There maybe a brake light fuse also. Do you have a third brake light as well? Does it work? Quinn , Arizona

I would replace the starter and /or battery. Both can be checked at a parts store. Sounds like you may have a short in the starter, draining the battery.

When it's running is the ignition light on? Otherwise, might the battery require renewal?

it sounds like you have a short some were im guessing it's in your tail light were it plugs in check and see if theres any open wireing from the light to about 3to 6 inches away

Have to make sure the battery is good,(first thing you do) & voltages are good,battery & alternator engine running Then look at scan tool data You NEVER Replace ANY Parts Why would you replace a part,if have not done any testing, to find a problem, requiring a part ? It back fires,that tells you something Did you check bulletins on that vehicles problems ( Failed Intake Gasket )from the Dex-Cool,is as possible You Tube Video some problems with that motor

the only connection between the two circuits is the common ground at the taillights, check those sockets for proper ground
