To get any real valid input on your problem you should provide your truck info, such as year, engine, cab type, etc. I think you mean "combination relay", not combination switch. I'd recommend you check EVERY fuse under the hood and also in the inside fuse panel as a start.

Making the assumption that you have a 2nd generation Tundra, the only thing I could find common to all three of those is a 7.5 amp fuse labeled LH-IG. It should be in the fuse box under the dash.
I suggest that you replace it even if it appears to be good.

I had the same issue when I blew a fuse under te drivers dash when installing led switchback lights. Check the fuses. Make sure you check each one because I believe the fuse listed did not say tail lights. It was another fuse that you did not think would be related. May have been the cig lighter one.

OK, this is the ONLY thing that I can find common to those!
There is a grey 13 pin connector J77 located behind the radio that provides the ground to those circuits. Maybe that got disconnected somehow??
