VW
did something really messed-up, and they did it for years. For some reason, VW has built some
parts of our cars to fall apart after a few years. There's a part in your dashboard called a blend door. The blend door is a flap in the
dash that directs air to your heater and dash vents when you turn the knob to the
red. The blend door makes for infinite and immediate adjustment of dash vent
temperature, and is actually a really clever idea. Here's where I believe
VW screwed it up. Instead of making the door out of a solid piece of material,
they made the door out of a piece of galvanized steel with 17 huge holes
punched in it. Then they glued foam to both sides of the door through
the holes. It works great for a few years, then it doesn't. The foam falls apart and has the
very dangerous effect of blowing small chunks of decaying foam into your
eyes through the vents while you're driving. And less dangerous (but just
as annoying) is the blend door no longer works well. With
large open holes in the blend door, full heat or full cold is no longer
possible, because the air just blows through it. I'm very surprised that VW hasn't been sued about this ridiculous
problem.
So
why did the manufacturer choose this assembly technique for at least 35
years? I would think that VW would have caught on if it was done by mistake.
For decades I believed that this assembly technique was used to reduce
noise inside the dashboard. But lately my opinion has changed to a more
cynical explanation. If VW makes the A/C and heat system to become useless
after 10 years, then the car won't be comfortable to drive and the car
will be discarded. Thus, the owner will need to return to the dealership
to buy a new car. I believe a kind of lucrative sabotage of their own
product. Not to mention a great disservice to their buyers.
Well,
OUR customers don't have to be forced into a showroom and huge
monthly payment$ to have a comfy VW. We'll take care of that pesky blend
door once and for all. After this repair, you can choose the temperature
coming out of your vents from burning hot, to bone-chilling cold, to anywhere
in-between. Check out the photos here to see how we do it. Oh, and we
can also install infotainment in any car - no matter the year, with new-car
style bluetooth for hands free phone and streaming phone media for iphone
and Android. I mention that here because your whole dash has to come out
to do this work. What better time to install a new stereo?

How many freaking holes did they need? ONE is too many!
Save
money on labor overlap.
This work is usually done with the heater core, an A/C evaporator, or
on it's own. Once the expense is taken on to remove the freon, coolant,
dashboard, console, heater and A/C case, we prefer to clean house and
take care of it all. So, while we're in this deep we encourage our customers
to take advantage of the labor overlap. This work usually runs about $1,000.00
to $1500.00, depending on parts costs for the different models. To put
it into perspective, that's the equivalent to 3 or 4 average car payments.
