While out of town, vacationing and touring for fall colors, I lost all power to the climate control system after a short coffee stop. When I started my Explorer I notice I had no heat, fans, defroster or power to the climate control system. Thinking I had blown a fuse, I opened the owners manual and checked the fuse diagram pages for the system that was not working. I checked all the fuses indicated but, I found none of them had blown. After detouring and heading for the local small town, I purchased an emergency fuse replacement and tester kit as it was now getting dark, trying to continue re-checking any fuses (while in the confined and most awkward place to install a fuse control panel under the dash board on the drivers side) was going to have to wait till daylight. On my return to my campsite I change the head lighting from auto to manual and pulled out on the knob to turn on the fog light system. As I did this all power to my climate control system returned and was working normal again. This could have been a real problem as the next morning I woke up to frost and 0` temperature and overcast for the day.
