Does the dash have to come out to get the blower out and back in.
Bentley says no. Just remove the lower panel and then the glove box.
Well I have gotten the cover out but had to disconnect the blower from it. Also loosened the engine compartment screw and the end screw in the dash to get that far.
I think bentley has a secret or is wrong.
The parts don't look the same as in bentley. The blower is mounted horizontally instead of vertical.

Let me answer how I got it in and out.
Loosened the dash stays and wriggled and flexed it out and in. Pretty crappy design but hey 50mpg.

Ya, but, what vehicles are "easy" to do this sort of job? The pess runs down my pantleg thinking that SOME DAY I will need to do a heater core in one of the Mk. IV's I have. The last Mk. IV diesel I put back together had a dash fire (blower switch failure) and I had to totally replace the dash and underlying plastic super structure to bring the car back to life. At the time, I was short of money (totally went through the ALH as well) and wimped out on replacing the heater core.
Now....looking back....I should have robbed the liquor store and gotten the money.............

I hear you about switches going bad. Particularly ones that carry a significant amount of power. If there is any loose connection that causes increased resistance you get a lot of heat.
We had a water heater do that. Someone didn't tighten the power connector down well and after hundreds of cycles it got hot causing the electric water heater to catch fire.

Had a 2 hr road trip today. New fan moved a lot more air and was quieter.

And they said Resistance is Futile! They didn't take into account 240 VAC.

The New Beetles have a motor blower switch which (with time) internally fall apart and make multiple contacts. The Jetta switches are slightly larger but do not seem to have that problem.
This Beetle was owned by a woman who had to have the blower all the time and constantly monkey with it to make her "self" comfortable. She called the local cornholebob fire dept. and they set of a bunch of "dry" chemical extinguishers in it to "put it out" (tell-ya-w'at!) (visions of Hank Hill).
Well, dry chemical is NOT dry and it is formulated to draw itself into anything with the opposite charge (as in electrics). Imagine how much work I have in this car.

You do not have to take out the dashboard to take out the blowers, it depends, because in each car it is a bit different, in some you have to, and in some unfortunately you have to, but I know how to give your mechanic to the mechanic and they will do it to you

On my 86 german jetta the dash had to have the bolts loosened.
I tried a hundred ways of twisting the old blower to get it past.
In the end I took the bolts out on the right side of the dashboard and loosened them on the left.
The new blower moves a lot more air than the old one.

hey guys,
so i replaced my heater core this weekend because it was leaking. So now when i turn on my heater it gets hot for a while and then the air gets cool and then back to hot. It seems like its in a cycle.
What do u guys think the problem might be??
Could it be a bad heater control valve or a vacuum problem?

Maybe air in the system?

What model VW did you do the replacement on? The early Rabbits and such did not have vacuum controls unless it got AC.
