I just fixed the cold starting issue on my wagon, and now another pops up. None of the brake lights work, including the middle one in the hatch window. I checked the fuse and replaced it even though it looked fine. I took a wire of the Brake light switch and touched it to the other wire, with no results. I have power at the fuse, and through the switch, but nothing at the sockets. All other lights are working fine, and the warning light in the dash does not come, as it usually does when there is a bad bulb.
Edit: For whatever it's worth, the temperature here has been unusually cold(getting down into the teens at night). Does temperature have any thing to do with wiring/connections/switches/etc?
If it could be a bad ground, are there any key places to check?
Any advice, tip, help is appreciated.
