GMC NUMBER: 91-9A-153
GROUP: 9A Audio Systems
DATE: October, 1991
CORPORATE NUMBER: 161003
SUBJECT:
AM RADIO INTERFERENCE OR STATIC (ADDITION OF RADIO GROUND KIT)
MODELS:
1985-1991 M/L VANS
Some 1985-91 M/L vans may experience ignition static, popping, and/or a whine noise on AM radio.
To repair this condition, it will be necessary to ground the engine cover to frame assembly, using an engine ground cover kit (P/N 15665468).
For 1989 and prior vehicles, the engine cover should be grounded using braided mesh ground strap (P/N 06287160) or equivalent and the rivet and
washer provided in the service kit. A flat washer may be necessary to install the braided mesh ground strap to the cover. This washer is listed in the parts
information below and is not a part of the service kit. The service kit has been incorporated into 1992 production vehicles.
If condition remains, it may also be necessary to ground the radio antenna at the coaxial connector.
