Symptom: Air coming out of A/C vents very weak.
Diagnosis: I traced the vacuum line through the firewall and to the T fitting where it splits through the vacuum check valve and to the intake, and the other direction goes to the vacuum canister.
From the T-fitting to the intake I removed the vacuum check valve,
tested it, then cut the ends and reassembled everything on the hoses. This is OK.
I removed the vacuum hose from the T-fitting to the vacuum canister, checked to see no-body was watching and attached my "pulmonary pump" to the vacuum hose. (I blew into the hose).
The air flowed freely -- something was shot. I looked and looked and could not locate the canister. Correction - I could not ACCESS the canister. So, at the T-fitting I sealed off the opening with electrical tape and tested the vents. Great air flow - it worked.
So, now what can I do about the canister? Can I buy another one, mount it somewhere else and run a new line?
Thanks!
