The vacuum actuator has a leak and will not release the parking brake. Vacuum leak caused havoc on heater control, engine idle, and o2 codes. Runs much better with plugged.
Need help replacing the vacuum actuator. No listing from GM; discontinued. Canister simply pops off and can be replaced but no part no.
Any help adapting other vacuum actuator application? Metal canister 2 inches diameter and rod 2 inches long with dogleg to connect. Has metal collar that snaps into ears on the parking brake frame.
GM must have used this actuator for other applications and other years.
Thanks for the help.
have the same problem?
