1995 Ciera 3100 intake vacuum question - ACSRY

[david3100]

There is a vacuum hose that runs off the upper intake plenum near the alternator. It is rubber and heads toward the coils. There is a one-way valve there and then a pink hard plastic line that is shattered on mine. According to one diagram I have seen it is "Acsry" meaning that it controls the vacuum operated doors under the glove compartment.
Can someone tell me where this attaches at the firewall? I would prefer to replace the hard plastic line if possible. I may have broken this line while replacing the crankshaft position sensor or the set of coils. Any help is appreciated. David

That pink line is the air conditioner controls vacuum supply. It is bundled in with the A/C wirin harness. There is a harness going to the blower motor speed resistor, and that line normally goes into that harness. If the exposed end is rotten, you can peel back the harness tape and find there is some solid vacuum line inside which has been protected from the elements. You can connect it there.

Sincerely,
David

Thanks. That fixed it with some 5/32" vac hose.
