In this video I can see you have the console vent position set to cold (blue) when pointing that digital thermo reader! Great video on how to change and check the heater valve though.

Yes, I realized that afterwards but forgot to reshoot the video. Thanks for the comment.
Nice one cheers, I am replacing the heater control valve on my E46 M3 so have the version with 2 solenoid pumps, same job and seeing the use of the c clamp was really genius as saves having to do a coolant flush and extra faff/mess. Cheers!

One of those 2 hoses that come through the valve is leaking. Do you have a DIY on replacing them?

No, I do not but just probably need to take off the hose clamps to remove it and then get a new one and refill with coolant.
Thanks for the vid! What's freon?

Air Conditioner refrigerant.
What hose is the that was on top of the actuator that you moved? ( you mentioned its a vaccum hose) where is that connects too? Pls help.

If I recall that's the hose that goes to the purge valve which is attached under the right side of the intake. The other end connects to a hard line that goes back to the charcoal canister.

No, it only controls the hot coolant going through the heater core.
Which hose goes directly to the heater core? I’m trying to clamp it off to see if that resolves my warm AC issue

Sorry, I can’t remember which is in and which is out. Although if you clamp either one of them you stop flow through the core.
Do you need to bleed the coolant system after replacing the valve?

I lost very little coolant so I just drove the car and checked the reservoir and topped it up over the next few days. If you lose a lot of coolant you will need to bleed the air out.
I have constant 12v and ground at connector even with car off?

I don’t have the electrical schematics to say what the ignition off default should be but it sounds like you have a short in your 12v feed somewhere.
My value is not heating up does it mean it's bad?

It could be, but it also could be the signal is not getting to the valve to open. Did you check the fault codes?

Can this cause pressure to blow the expansion hose
@JRsGarage
8 ай бұрын
No, that might be a blockage in your expansion tank causing it to not vent properly.
Did You solve the problem with temperature diffrence in vents?
