Mein Auto: 1984 733i
How can I get my heat back on 733i?

Hello--

New to this forum. I have a 1984 733i that probably has 450K on it....The only thing that has been replaced is the water pump. I had the transmission rebuilt in 1995 because I by the time I changed the fluid, I had waited waaay too long.

Anyway, I have kept the car on full heat setting for years because the last time I had turned the temp setting to cool, it almost didn't make it back to providing heat....and that time it made a clanking sound when the heat was coming back on.

Now, it just blows room temperature, no matter what setting it is on (up/down, auto, etc).

Heater control valve?

Heater diverter valve?

Not sure, but for one of them which is located in the engine compartment, top passenger side on the firewall, I took the hose off and found nothing blocking or closed in there. I flushed that system out with a hose (some darker gunk came out too) and refilled with proper coolant after it was flowing clear water. No luck.

I don't have the bucks right now to fix, the rest of the car runs great. Operating temp is normal, drives fine. No coolant leaks inside the car foot wells or on the ground.

I'm hoping for an easy fix suggestion that will let me keep the heat flowing on the floor at all times. I don't need to adjust anything for cabin temp. Something I can do myself that won't cost me anything. I don't mind bypassing valves if need be.

Thanks!
