    Hello. I have an '86 Silverado with a leaking HVAC vacuum selector valve. I dismantled it to see if it was repairable and it appears that the plastic backing plate is cupped with age. So I cleaned and reassembled it and it's still sucking in air. It also now has a broken retainer tab :)
    I've been searching online for a new one and everywhere I look they're out of stock. Anyone know where I might be able to buy a NOS or aftermarket one of these?

    Thanks Craig. I looked at buying the whole HVAC control assembly as well but as rest of the assembly is in great shape I really wanted to get just the valve.
    I ended up buying a reconditioned valve (15-71032/16037768) from Tom at [email protected] for $29.

    Turns out it's the same part as the original ACDelco 15-17220/GM 16037769. Not really sure why they are coded differently. I even disassembled both it and the original to verify the vacuum channels in the rubber seal are an exact match. They are.
    I installed it over the weekend at it works great.
