Hello All,

It has been a while since I have posted to this forum. I do miss you all.

I have a interesting issue on my 87 944 N/A.

While driving my heater does not seem to be blowing all that hot. It's more luke warm. With the fan speed set to high or set in the middle. Occasionally it will get as hot as it should but then cool back off.

If I put on the defroster it will heat up but I haven't tested enough to see if this is also intermittent.

Any ideas?

You've got air trapped in your cooling system.

Bleed the system...and then bleed it again.
