heaters in da MK2

[86gti]

to all the mk2 owners......how well do your heaters work???
if im driving at bout 100 with the fans off it gets pretty hot inside after a fair while....but when i turn the fan on around town and just after the temp comes up on a cold morning, it seems like there is a 50 a day smoker blowing through a maccaz straw...the fan works, but hardly blows atall...!!!
not good when your windscreen foggin up!! once i get moving for a bit and the air is forced through its ok, but the fan is useless! .....even a 57 beetle heater is better ..hahaha
is this usuall??? or am i just used to jap crap heaters blowin my hat off in the back seat......

my heater works great. definately sounds like something is wrong with yours. does the blower work at all, does it blow cold air?

My '86 worked great.

you can hear the fan spinning, but wont blow hot or cold air.....
can only just feel the air if you hold your hand infront of vent.
with it on hot and driving at 100kph with the motion of car pushing it through it heats up inside nicely. seems like maybe fins broken off fan or something, mite pull the fan box out on weekend n have a squiz

Does it have air conditioning?

g' day there my mk2 fan & heater work great, but i could do with a regas ffor the aircon.
i have heard afew time s that the heater matrix in the mk2 is prone to breaking down though, or it could be the power supply. they are something that pops up on ebay uk quite often

I always suspect the heater matrix`s as they always break.

Could yous be ducting come loose under the dash?

Take the glovebox out and stick your hand up there and see if you can feel any breeze.

OK, I have had a similar problem before with a '88 16v from SA.

There is a slider that controls which vent the air comes out of that operates vacuum servos. It works by a rubber piece with holes in it sliding across and connecting different ports to open the various flaps.
The one that I had was not drilled correctly so that when a vacuum was applied to the rubber pad it closed off a minute piece of rubber and blocked the port. It took a while to find as at first we were blowing through it which opened it up. Then when I sucked on it I noticed that it closed up and blocked the vacuum.

There is a test procedure for it in the Bentley workshop manual.

im going to have a peek later on sat..the vents all work fine...doesnt have AC..the heat comes out of the vents while you are driving, feet, windscreen, mids etc, but just wont blow heat when stationary with the fan on....ill do some investigating and let you all know what i find

Is you car left outside a lot? Have you cleaned the leaves and crud out of the rain tray on the firewall. You might find the air chutes (under the mesh covers) are choked too.
