my car is a 1979 320i and i just bought it with an '81 m10 swapped in it. my problem is that i cant get heat inside the car. i thought it was the thermostat, which needed to be replaced anyways, but i still cant get any form of heat in the car. i live in northern minnesota and its january so i kinda need the heat! any help would be nice. i am newly into the old school beemers so i am not very knowledgeable with them yet.

first off, is the engine developing heat? Does the temp guage rise in a resonable amount of time? It should since you fixed the thermostat.

now, if your engine is at proper running tempterature and you don't feel heat there are two things to look at next:
(1) Is your fan working?Even if it isn't working, you should still be able to feel some heat when you are traveling at a good speed since air will be coming through the grill.
(2) More likely your heater control valve is broken or the wire connecting the switch on the dash and the valve has broken. I had the wire break on my 02. To isolate the problem, go inside the engine bay and if you can get access to it, manually turn the heater valve. If the cable is broken this will allow you to turn your heat on. If you still have no heat, then either your valve is broken or you need to look further into the situation.

Check for fluid leaking (coolant) into the cabin. If the heater core is cracked it will leak fluid into the cabin when the heater vavle is open. This is unlikely because you would have noticed your radiator fluid dropping and your carpet getting wet.


Lastly, depending on the quality of the swap, there is a chance the heater was never hoooked back up. Someone might have botched the job and taken the heater out of the cooling system loop to save time and effort. This is easy to see, just look at the back of the engine bay and make sure there is a cooling hose running from the engine block or head to the firewall area. The heater core should be located behind the dash, so a hose running behind there is a good sign.

Hope this helps out some. Get back to us on your results.

Hey,
its me agian. i did some searching and found that my heater control valve is not on the firewall. it s under the dash somewhere. all there is there is the two hoses which conect to the heater core under the dash somewhere. both hoses get hot so i know the "juice" is flowing throgh them. the top hose gets the hottest so i assume its the in hose and the bottom one gets a little warm. could my heater core be plugged a little bit or ?? also, how do i get to the heater core. i cant seem to find a way under the dash. do i have to dismantle the entire dashboard? i hope not! i do get some heat when i first turn on the fan, but it quickly dissapears so thats what makes me think that the core is kinda plugged a little bit. do you know a good place to get a "service manyal" with good pics. especially of the dash and such. any good websites that would have a diagram as to how to do this? any help is muchly appreciated. agian i live in Northern Minnesota and this friday is suppossed to be -17 degrees for the high! so i need the heater! also, my fan switch is shot. went to turn it on and the fan didnt work. hope its just the switch and not the blower motor, any insight on this?

talk you later

check your coolan cause it might not be enough to open your thermostat, and if you have enough coolant, then check your thermostat, they're about 30 bucks canadian, if you get a good discount, and then after that you get to the expensive repairs.

sounds like a clogged heater core then, i havn't really looked to see how to take it out, havn't had heater problems thank god umm but i doubt you gotta take the dash appart that would be a pain in the A$$ so hopfully not, but take it out and get it recored, its prolly cheaper then getting a new one, and get it presure tested.

thanks for your advice. i hope that i dont have to take the dash totally out. i am trying to find a service manual, but aint having too much luck around here. i live in the middle of nowhere. i think the heater core is on the drivers side cause thats where the hoses come in from the firewall.

well, wish me luck and if you know of anywhere i can get diagrams of how to do this; that would be greatly appreciated.

thanks again for you help.
