My automatic climate control hvac fan works intermittently.  I start the
car, then the fan tries to come on, it puffs and puffs, finally it runs.  It
acts like the power is being switched on and off..  Its getting worse as
time goes on.  What could the problem be. Help.

My expedtion has 18,000 miles on it and the steering wheel started shaking.
I took it to the dealer and they told me I needed  4 new tires because of
cupping. I saw the tire that ihas the cupping. The front driver side tire.
Do you think if I rotate the tires the cupping with fix it self. Seems
crazy to me to have to buy 4 new tires at 200 a piece when I only have
18,000 miles. Has anyone else had cupping troubles?
Btw the dealer was not very helpful at all!

I have a 1996 Ranger. The check engine continues to comes on. The code
reads as a faulty EGR valve. I’ve replaced it twice as well as the O2
sensors and still no luck. Any ideas????

Include make, model, year, engine, engine type, transmission.

Also if you have read out codes, include the code..NOT what you or anyone
else interprets them as.

MAKE SURE to include ALL symptoms, whether or not YOU think they are
related.

ALSO anything you did immediately prior to the problem, to include even
raising the hood to check the oil!

I know it sounds dum, but why waste hours exchanging questions and info
when you dont have to?

I am looking for information for someone and can’t seem to find
anything.  They are looking for some type of wiring diagram for a 1972
Ford F-700.  They bought a new motor for it and I think they need help
with some of the wiring.  Is there any place I can find some wiring
diagrams or anything else about this truck that might help them?  Thank
you for any help,
Chris
