2003 Ford F150 V8 Four Wheel Drive Automatic 60000 miles
F-150 supercab Lariat with V8 5.4 triton off road fx4. The electronic 4 wheel drive work earlier today. When I got to a plowwed road, I selected 2 wheel drive, then re-engaged the 4 wheel high. The dash light lit up, but only two (rear) wheel drive. I never used 4 wheel low, but tried it, sounded like it engaged, but not sure if it also is working. Do low temperatures (low 20's) have an impact on this electronic system?
