Heater won't work - I think

I got it from eBay seller
Oem_parts_only

I can try and get you one if you need let me know. I saw a few just look up the part number.

That certainly looks like corroded terminals and hopefully is the cause, worth checking gaskets as it must have failed somehow, good diagnosis !!!! Well done!!

We will see after I install the new one. Hope it solves the problem.

I appreciate the info on the part seller. It is hard to find used parts for a BMW. Most junk yard sellers don't like selling off the smaller less expensive parts. There are quite a few failures for this particular part on the heater system, making me lean towards a new one. It is interesting that the coil is shorting out, not allowing a on vehicle repair.

Thanks

Herb I got a used one because I don't know 100% if this part is the culprit.
I say this because when I first push the defrost button I here the blend doors moving and for a few seconds I feel lots of heat then it just blows cold air. So I could have multiple issues or maybe keep my fingers crossed this part will fix it. Got the part today in the mail I'll install it soon.

You know what this means? I got heat flowing again!!!!! Yahoooo!!!!!!



Now it's Time!!!!!!


I replaced the heater control valve that I had ordered after finding the shorted solenoid and it worked like a charm.

Thanks to all that helped I love this forum!!!!!!!!!!!

Glad you got it working!

I owe you a brew!!!

Good work, and for the benefit of others good diy and diagnosis!!! You can drive upto the North East now and be toasty warm lol

I wonder if my heat works? Wait, never mind, I don't need it!

Very nice diagnosis and fix Nitrogen.

Nice fix Nitro! The power of bimmerfest and some good DIY talent.

Ok well thanks to all that helped get my heat back.

Don't laugh but as I first stated I had a small coolant leak toward the back of my engine. I thought the dreaded curse of the coolant pipe had hit. But after I fixed the heater control valve no more leak.
Can it be? Could the valve cause the pressures in certain areas to go high and leak? Very interesting? I looked at the hoses while doing the replacement and one hose was bone dry. What do you guys think???

Good job on the fix Nitrogen. I will buy you a beer if we ever meet!

Hi I do not know how to do it but you should consider putting this in the DIY section, as it is an excellent bit of fault-finding to benefit others!!!

Thanks 645/333 I don't know how to transfer it to DIY maybe someone else can help with that.

I just can't believe that the leak is gone now to after repairing the valve. It was in 2 different locations. bizarre!!!
