My passangers side has cracked for the second time , still on the original drivers side.

 

In facted one of them cracked in the first 100 miles. The cracks appear to be from heat. Never had this problem in my other cars and trucks. Yet my Lightnings both were cracked the first month. All my 2nd Gen Lightning buddies cracked too. Ford must have used a crappy vender on these fog lights.

 

My foglights are on all the time with my autolamps. Cracked the passenger side last winter, it's due to the internal heat of the lamp and the external temperature of the air. It will happen even faster if there is a cold rain while driving with the lamps on for a while. My dealership is run by a bunch of ********n d**ks that would not replace under warranty, they wanted $180 to replace. I got replacements for my 2000 from www.texasmustang.com, because they are the same as 87-93 mustang for $17.95 a piece part number E7RR-0015L203-L.

 

I have a 2000 L and have only used my fogs about 5 times. They cracked with about 10,000 miles.

 

I wired my fogs to come on w/ the headlamps also. They cracked recently. I have moisture in just about all of my lenses....rears, corners, etc.
