Turn signal problem

I recently purchased a 1999 Ford F250 Super Duty withba V10. On cold mornings my turn signals won't work but my flashers will. Turn signals only work when the cab heats up and get warm on the inside. I found the flasher that works both the turn signal and Hazzard lights. Right next to the flasher are two little five prong relays. What are they for? And also what could cause my turn signals not to work when it's cold in the morning? your help would be greatly appreciated thank you.

Probably the multi-function switch or its connectors.

One is the fuel pump relay. The other is the trailer running lamp relay.
