Hey guys i just recently had this little issue with my fogs and was wondering if anyone could guess what it is. So, i have my fogs wired to turn on when u start the car and they turn on seperatley without the DRL's. But now all the sudden the fogs will turn on when you put the car to the on position but as soon as you crank the car and go to start it they turn off and you have to flip the switch off and then back on for them to turn on. I can't figure out why because its been working fine for a long time now and it jus started doing it after i took the car to toyota to have them replace the intake manifold, but i don't see why they would have touched anything to do with that? Any ideas?

Obviously something happened. Your task is to retrace the fog light wiring harness all the way through, paying particular attention to any relay switches you might have and how they are wired to positive and negative. Sounds like a relay isn't working as it used to.
