Q: I have a 2001 Ford F-150 XLT that has map LED problems. It’s supposed to display outside temperature and compass heading. Nothing is displayed. There are two switches that turn on the map lights that do not work ,either, but the lights go on when I open the door. When I pull the unit down, there are a few components there. Do you know which one would cause this problem?
A: The most important step would be to check all the fuses. Also, check the right kick panel; all grounds for that system are located in that area. If you have power and ground at the unit with the switches turned on, and it still does not work, then the unit may need to be sent out for repairs. If the fuse and the ground are good and you still don’t have power at the unit, then you need to trace the wires for an open circuit. Most openings in that circuit are at the base of the pillar where the wires go up into the ceiling. Water and sand on the floor are the most common reasons for the wires to break.
Q: The steering wheel on my Toyota squeaks when you turn it either to the right or left. My mechanic does not want to touch it because the air bag is involved. The Toyota dealer wants $150 to lube the steering mechanism. I know it was taken care of last time it squeaked during a simple oil change at this same dealer. I feel that $150 is expensive. Any ideas? The car has 56,000 miles on it and my wife drives it 85 percent of the time.
A: If the dealer has to take the steering column apart, $150 is not too much to pay. Before you have that done, however, try spraying some WD-40 lubricant on the knuckles that are inline on the steering column. That has been a problem for some time with not only Toyotas but Hondas as well.
