Several months ago, Helfman Ford "reconditioned" the battery
in my 05 Expy. Since then the steering wheel controls have
intermittent failures, they sometimes work, they sometimes
dont. For instance, pushing the vent fan speed rocker down
will cause the temperature control to be set higher, etc.
But, the next time I turn on the Expy, the switch works OK.
Does anyone know what is going on here and how to fix it ?
It is not going back to Helfman, they have done enough damage
I am unsure of what anyone might do to a battery that would "recondition"
it.... At the same time (and this may come as a surprise), many of us have
no idea who or where Helfman Ford might be....
Now... if the worst thing that Helfman did was charge or disconnect the
battery, there should be no effect on the redundant steering controls... If
there is a part of the story not being told.... well, what can I say?
The redundant steering controls work on a series of stepped resistances that
are deciphered by the powertrain control module. This programming is "hard"
so disrupting the power supply will not "erase" anything.
So.... Helfman Ford may have left a bad taste in your mouth... but, with the
scant information given, we cannot categorically state that they are the
cause of your current woes - this may, indeed, be coincidental.
As it stands, the system is quite complex.... obviously, it appears that the
PCM is likely seeing resistances
One can only love fat, old fingers and Windows "hot key" combinations....
It would appear that the PCM is seeing resistances (commands) that are out
of line with what is desired... I can only suggest that you find another
shop... a shop with the required tools and manuals, to address your concern.
Yes, it was a bad servicing. They also blew out one of the hoses to my
transmission cooler. I noticed the next morning when I had transmission
fluid in the garage floor and the transmission was slipping.
I suspected that but wanted to confirm it.
Yes, coincidental <g>. Nothing that can be proven here.
Ah, so that would account for the intermittant behavior.
This is not a terminal problem, just an annoyance, so I am going to just drive
for a year or two more and trade it for something else when it hits 100K.
I would love to have a small SUV with a stick and a diesel, maybe one
will come available by then.
It was a grand cherokee with an automatic and mercedes v6 diesel.
I want an I4 diesel with a stick. Of course, you can get a Wrangler
with a 2.8L I4 and a stick anywhere in the world except in the USA
where they are made.
Because then we started arguing about the bad brake job. I
finally got that fixed at Midas with new brake rotors. Helfman
Ford turned my brake rotors and left 1/16" grooves in them.
My brake pedal routinely went halfway to the floor before things
But the other rocker switches (cruise control, radio volume,
radio station jump) all still work ok. The only steering wheel
switches that intermittantly malfunction are the vent fan speed
rocker and the A/C temperature rocker.
