TSB for replacing the blower control module?

[Miekk]

Do I really have to do do this TSB?

Per the dealer, I ordered part 9L3Z19E624B which is not the number in this TSB, but I thought I'd ask. Did they upgrade the part?

That Heater blower control modual is the same as the electronic resistor.

Why not let them do it? They don't charge and you don't have to do the work.

I thought if your car was out of the factory warranty, you have to pay out of pocket for a TSB repair? Not covered under warranty.

Stupid question, but here go's anyway. Does replacing just the resistor fix the problem, or do you have to perform the wire cuts and splices? Any idea what Ford wants to complete the TSB?

It still costs you money. Tsb's are paid for by the dealer and it costs you nothing.

Update.

1) The old part number 7C3Z-19E624-C has been replaced by 9L3Z19E624B and no longer requires the rewiring TSB in previous posts.

2) $52 from Tousely Ford

3) TSB's are NEVER paid for by the dealer unless you are within your factory warranty, extended warranty that may have been added by Ford to the effected parts reguarding your particular situation or they are generous for whatever reason they deem fit.

Thank you.

Thanks for the confirmation on the TSB's. I thought I was getting hosed by my dealership.
Guess I am getting that part to avoid my a/c going out this summer.

Have a 2007 EB and two to three times in the past had the HVAC change air direction (defrost for example to upper or lower vents) and velocity (from low to high) without any direction. Earlier today, my wife complained that the HVAC changed vent location and even temperature without any command. It seems as though having the system on AUTO has no effect on when this happens. Is this TSB supposed to fix the problem? Thanks.

Wednesday morning bump. Anyone got any ideas if my issues are related to this TSB ? Thanks.
