Q: I have a
1994 GMC pickup. When it gets cold it is very hard to unlock the
driver door. A couple of times I have had to unlock the passenger
door to get in. We tried spraying WD-40, but that hasn’t seemed to
help. What could I do to make it easier to get into my driver-side
door in the cold?

WD-40 is magic stuff, it is not the best choice to lubricate
automotive door locks and linkages. Although it does a good job of
cleaning and temporary lubricating, it goes away, so it makes a good
first step. Graphite has long been a popular lube choice, but we
like to use bike chain lube. Many of our readers and locksmiths
swear by Tri-Flow lubricant.
constantly have to put air in the tires. The service adviser says
this is because I have alloy rims and they corrode due to salt usage
in Minnesota. Is this legitimate? They will clean the rims at a cost
of $35 each, which I think sounds exorbitant, and wonder if this is
something that Ford should correct.

A: It is true
that salt and alloy wheels are often a problem. Since this is not a
factory flaw, the car company will not work with you. And it is not
only Fords that have the problem. One solution is to buy a set of
steel wheels and mount winter tires on them. Store the alloy wheels
until spring arrives.
Q: Is it true
that eventually, all moonroofs will leak?
A: It is not
true, but the onus is on you to perform regular maintenance on the
windows. First, avoid parking with the sunroof open where dust and
leaves can get into the drains and clog them. Second, apply silicone
to the rubber seals at least once a year to keep them supple and
reduce the chances of tearing. Third, keep your glass clean.
Q: I own a
2015 Silverado 1500. My truck came with basic wheels and hubcaps and
I want to upgrade to 18-inch aluminum rims. The truck came with
17-inch rims. What has to be recalibrated to compensate for
speedometer, odometer, etc.? I am getting conflicting answers from
mechanics and dealers.
A: You will
have no issues with the speedometer, odometer or ABS system if you
maintain the original wheel-and-tire diameter. That involves
installing lower profile tires on the larger rims. In this case, you
would probably need to go with 275/60-18 tires.
