Anyone had problems with the fog lights not working on their 2006 Jeep Wrangler Unlimited Rubicon?

I've had it at the dealer 3 times to fix the problem. Each time, they simply replace the fuse. The fog lights work before I leave the dealership. Then, when I drive out into the country on the weekend, surprise! They don't work! I haven't abused the car or taken it off road, so that's not a cause. My brights work..and I know you can't operate your brights and fogs at the same time...it's just getting frustrating! I've read about other complaints about chrysler vehicles, and how corporate is very non-reactive to consumer concerns...so it seems contacting corporate may be a dead end. The car is still under warrantee , but if this problem persists over time and the warratee runs out, I'll be stuck paying for this repair...which makes me wonder, should I be looking for a lawyer, so Jeep wil fix this once and for all? (or, if not, I won't be stuck paying for it?) BTW..everything else with the car is fine...Any input is appreciated..thanks!
