2005 Acura TL right high beam works intermittently

On and off by them selves is usually the light switch. If you loose the low beams and have to pull the turn signal switch on and off to get them to work, replace the turn signal switch.

Dennis, Make sure the low beam bulbs are OK, first. if fuses and grounds OK, it will be your multi switch, which you nay be able to disassemble and clean contacts.

How to Fix Low Beam Headlight

Low beams out high beams work

Acura TL Headlight Replacement WITHOUT removing the bumper

Your best bet is just go to your nearest junk yard and get both headlight assemblies you can't just buy the warmer piece you have to purchase the whole thing

Have you tried testing the cables? If you don't have a tester you can use a bulb and some wire. If you find there is no power ,it is time to start tracing cables and look for a break. Good luck

If the high beams work it's not a blown fuse causing the low beams to not work. It seems possible that the low beams are burnt out, or the dimmer switch may be at fault.

2006 RL headlamps are similar to 2005 TL headlamps. We owned a 2005 TL (great car). The headlamps are HID (high intensity discharge) and many people don't like the sharp cutoff that they have. Your only option other than driving with the high beams on is to have them professionally re-aimed. This may or may not help the problem. Take it to your Acura dealer and talk to the service department about this.

Sorry, I wish there was any easy fix.

in this case make sure you have voltage going to the low beam lights. 12 volts. you need a volt meter. if you do not have volatge you have to check and make sure power is going through the fuse. a bad fuse will be broke, but you can have a good fuse with no power going through it. if you have power going through the fuse you have a wiring open somewhere between fuse and whatever is between the headlight connecter.

plz check and get back i will keep checking on here on and off.

If your car is running daytime running light system .. there is a DTR relay that goes defective and needs replacing ... I had the identical problem that was fixed with this replacement. The DTR relay is behind the glovebox.
