thread on resetting, assuming its got a black olive valve fitted,

even if its had a new original style valve fitted the seals harden and leak even though the valve looks perfectly serviceable, and it only takes a sniff of hot water to make the cabin unbearably hot

Although I have a B-O valve, as most of us do, is that resistance value a good way of checking that an original MGR valve is at least (attempting to) close off correctly, or is that in some way different?

Its a long while ago since I developed my valve, but Im sure I used a good original valve to check the cold resistance and Ive used the same actuator so I would say yes.

Having said that the actuaturs are a bosch part and very reliable, unlike the valve itself which the originals were made in mexico, presumably from recycled bean cans

Hi, I also suffered with the inability to turn the heater off and last weekend fitted the black olive valve that came with the car (14 months ago!). The old unit was in a sorry state and with the valve driven closed, I could still blow through the port that connects to the heater.
I can confirm that the new valve is simple to install, the top tip from me would be to invest in a wiper arm puller available cheaply from Ebay. The valve works a treat with no more unwanted hot air. I think you?ll always get very slightly warmed air as the pipe run from the bulkhead to the valve and back may have some heating effect?
Thanks to blackolive, It?s really great that that someone made what must have been a significant effort to devise this solution and make it available to all.

I have one but because my heater and A/C seems to work as it should I have never got around to fitting it.

Are there any instructions on how to set it up when I do get around to fitting it ?

Plenty of information in various threads if you search around a bit, Steve, but these should be a good starting point:
