Strange Blue Flashing Light? - Toyota Nation Forum : Toyota Car and Truck Forums

Hello,

I just purchased a 2007 Matrix XR a few days ago. Starting last night a tiny blue light began flashing near (behind near the top of the windsheild) the rearview mirror. It continued to flash all night and all morning on my way to work. Any ideas what this could be? I didn't find any answers in my owner's manual. The Toyota service guy I talked to said it was a sensor meant to help deflect other car's headlights. This doesn't make sense because it flashed in my dark driveway all night. Has anyone heard of this problem or know the purpose of the little blue light?

Thanks for your help!

do you have a remote start? i know my compustar remote start comes with a bright blue LED.

Yes! The car came with a remote start that does not work. I bought the car on the condition they fix it. This will be done in a few days. I haven't tried the remote start since the blue light started flashing. It looks just like a small LED light behind the rearview mirror. Does yours flash constantly? I just went outside to check and it's STILL flashing.

Mine only blinks when the alarm is activated. Does it only turn on when you turn on your alarm? That's probably just your alarm. Do you know which alarm/remote start system you have?

I had no idea I had an alarm! There is a small alarm button near the blinker but it's not anything you can push so I figured it didn't work. Not sure how to disarm it? Looks like I have a lot to learn about my Matrix. But so far it's the best car (besides the annoying blue light)!!

I do not have an alarm. Maybe it has something to do with the auto starter...and not sure which type I have.

You might have just have keyless entry but not the alarm yet if your dealer lost the aftermarket alarm fob. I think you have a compustar system but what puzzles me is how you can drive the car with the alarm activated...

A remote starter could have this light which is actually on the antenna mounted up behid the mirror.

Did you buy it used? Whatever that blue thing is, it's aftermarket.

Thanks for all of your input! We took it in and it was the auto starter just like you mentioned. Now it is working perfectly and no more constant flashing blue light. Thanks for your help!

Nice, no more cold car!
