I leave work and walk up to my car, press unlock, and hear "beep beep" but don't see the flashing lights.

I think...ok ?

Get in the car, drive home and press down the blinker....nothing. No arrows, no sound, no blinking, and I looked in the reflection of the car in front of me to confirm.

Come home, try lock and unlock again, and have the same issue - car does everything fine but there is no light flashing with the unlock.

Thoughts?

 

hmm i guess u can use a voltmeter to both sides of the signal wires one by one to see if there is any flow when activated.

 

check the fuse(s)

aftermarket alarm?

 

I agree...
Fuses - check the fuse panel

 

Fuses look fine...any other thoughts?

 

Give er' a reboot (unplug battery for 15 minutes)?

 

that happens to me when i dont "lock" the doors/car with remote to begin with. then when i go out to "unlock" it=no blinking lights

 

did you unplug your hazard button recently?

also you didnt answer earlier...do you have an AFTERMARKET alarm?

 

Turn signals will still work if the hazard button is unplugged. Confirmed this today.

 

check the blinker relay. i had this problem where one side stopped working.

 

Don't have an aftermarket alarm but recently had the side mirror blinkers/LED puddle light installed and I'm wondering if something may have gone bad?

 

very small possibility that the little extra load of the mirrors could have snapped a fuse.

 

try the fuse... if not, then the turn signal relay.

do you hear the relay clicking?

 

Check your connections + As others said, could have shorted a fuse or caused the relay to go out.

good to know. most cars wont.

 

Also, you may want to check your blinker fluid level.
