I bought a 1 owner 05 RL with 80,000 miles about 2 years ago. I’ve had some electrical problems that have gotten worse lately.

the passenger side headlight flickers and goes out every once in a while. (Just turn them on and off quick and it goes away)

my power windows stopped working twice

sometimes my key fob doesn’t recognize Driver 1 and all my settings are reset (after I turn the vehicle on and off problem goes away)

but lately i have my stereo stereo shut off and not work. Randomly and I get a check emissions and check awd light.

Again turn it off and on and it goes away

also my nav screen dome light and headlights flicker randomly

ANY HELP??

Thanks !

Most probably bulb needs changing. Switch bulbs over to make sure.

Odd. But, search on this site for the reset procedure for power windows.

I'm starting to suspect the battery. How old is it?

AWD usually follow the emissions one. You need to pull the codes and see. Can be many things triggering the emissions, mainly o2 sensor and/or cat converter.

Make sure you are tighteing the as cap a few clicks when you fill up and not just a click or two. That may trigger emissions too.

Didn't you already mention the headlight?

Nav flicker... well, do a search on this on the site.
