Have a e36 318tds coupe
My problem is the blower is working but there is no heat coming just cold air.
Im just wondering is there any common problems that cause this?
Car comes up to temperature as it should so its not a thermostat problem.
Any ideas?
Jack the car up, run her to temp, rad cap off, heaters on full, get a long pipe that will fit into the expansion bottle, fill it with water to allow you force any air out while turning the bleed screw on the top of the rad. Failing that I have a full matrix, panel and heater control valve available for sale for a coupe.
What will that process do the car is not air locked running and driving perfect. Thanks for the reply btw
I was more leaning towards there is something giving trouble with the hot/cold dial some valve not doing what it should?
I had a similar situation, car ran fine but no hot air. Was convinved there was no air in the system, bled it again and bingo. You could also take the valve off and check for blockages etc. I don't think the its the final resistor because from reading a post recently you would have no air blowing at all.
It blows but wont blow hot air for some reason. I will bleed it again and see might replace the rad also as its only in average shape.Quote:

Definite sign of trapped air, needs to be bled again properly
I had the same peoblem with my e36, I bled it and changed the thermostat still no joy. It was the heater valve, €20 in the scraper and dosent take long to change.
Id be suspicious that could be my problem where abouts is it? Coming from from the bulkhead somewhere?Quote:

Are them valves moved by cables or are they electronically controlled?Quote:

You sure your stat is operating correctly? If it's stuck open it can cause a few issues and seems as how you changed heater value and bled the system then maybe it's worth checking?!

Its been replaced also car comes up to temp as it should. There are a good few coolent pipes around that valve one of witch goes into some sort of black box sorry for bad description its under the intake mani. Cant find any info on what it does at all.Quote:

If it is the case it's the core/matrix on the e36 it's handy enough. Take out the glove box. Undo the heater valve. Undo the nut holding the pipe on the engine side of the bulkhead under the windscreen. 3 torx head screws holding the pipe work together. Use something to catch the water and when you remove the pipes the core will slide outward to you. There is no need to remove the full dash or housing for the matrix
Im convinced its not the matrix im going to pipe it direct from the engine rough i know but if i get heat then its some valve stuck or the dial in the car damaged. Id rather a clutch gone any day over this shit lol
Has this car got a cabin filter??
there is a good blow from the car but its blowing cold i dont think its the filterQuote:

The driver setting is always cold to prevent you from falling asleep but you should have hot air to the windscreen and feet.
You'll notice a blue colour near the driver setting. I thought there was something wrong with my car too at first but it's how they are :)
Lol are you serious i dont know weather to believe you or taking the piss.Quote:

Here you go :)

People always assume the worst when you post about a problem. I hope you didn't go through all the hassle for nothing.
As I said mine is the same its hot when pointed at the windscreen or feet but not the face. @[Super4] 's e36 is the same too, I thought mine was broken too but he explained it to me.
The analog system should still be warm just not as hot as the air that would hit the windscreen etc
It's stone cold on driver setting on mine anyway but if you kind of set it between the face and feet/windscreen setting you can get a little bit of warm air through. I'm guessing it's different with the climate unit?
I'm probably wrong it's been years since I've had an e36 with analog heating
I really don't like the analog, it's the one thing that bothers me everytime I sit in my car, but if it's climate or sunroof I'd take sunroof everytime but that just comes down to personal preference. I think it's silly a lot of e36s were specced with one or the other, one doesn't exactly cancel the need for the other. Can't be too fussy though, when you find a car that ticks all the other boxes sometimes you gotta compromise!
I'm happy with my knobs :) the digital is clumsy and confusing. It might look better depending on your opinion but it's a 90s car and the knobs are not out of place.Quote:
