This is on the '89 CV. When the car is in gear there is a vacuum hiss in the dash. It goes away when I get on the gas. I'm assuming it's the parking brake release issue like others have had. I can't remember what the fix for this was. Plugging one of the vac lines under the dash, correct?

That's the parking brake release then. I think there's a white T thing under there that you plug. It's been awhile, I'm not sure. SOMEONE here oughta know!'89 Ford LTD Crown Vic - '92 Ford F-150 Custom -

If your servo diaphragm holds vacuum and you like the auto release then replace the vacuum switch at the bottom of the steering column. If you do not care about the auto release and want a cheap fix then remove the switch and the hose conecting it to the vacuum servo, and plug the other hose and zip-tie it so it doesn't just hang there.Comment

What he said. Valve is a white half-moon shaped thingy attached to the top side of the steering column all the way against the firewall. Should be a hard black plastic line. Mine had a one-way valve that I was able to simply spin around and use to block the thing.86 Lincoln Town Car (Galactica).

Done and done. Unhooked both lines and plugged the black one. No more annoying hiss. Thanks for the help.
