2004 Caravan Anni. Edition - Exterior lights don't blink
I have 2004 Dodge Caravan Anni. Edition. When I used to lock/unlock the van using the key's lock/unlock function, it always used to blink all exterior lights. On first unlock attempt, it used to blink left side lights and if I press the unlock button again, then it used to blink all side's exterior lights.
But now something has gone wrong. I can lock/unlock the van using key's lock/unlock function but there is no blinking of lights. I am not sure if I can fix this problem myself or I need to visit the dealer to reprogram something.
This van also has head lights delay function. That is working fine. It turns off the head lights after 60 or 90 seconds I believe.
Can any of you please help me so that the exterior lights start blinking when I lock/unlock the van?
Thank you so much.
