Outer Limits 4x4 Board

Hi all,
I had problems with the head light and dip switch on a 92 rangie. The head lights were powered through the switch and after 19 years the switch was fried. I installed new switches and put relays into both main and high beam circuts. Now I have a problem where if the inside temperature of the car is hot say been sitting windows up in the sun every thing operates normally, when the inside cools down the indicators don't flash they just stay illuminated, as the temperature is dropping you can hear the flasher relay clicking away. Is this the sound of a crook relay or is the problem somewhere else.
Any thoughts?

sounds to me that it's a prob with your flasher unit.

Yeah my guess would be your flasher unit could be the problem. Just check all your flasher globes work then have a closer look at the flasher unit its self.
