Odor Correction for Chevrolet Venture 1998
The air conditioning system may emit odors primarily at
startup in hot or humid climates. This odor may be the result of one of the
following conditions:
| • | Debris in the heater A/C module |
| • | Growth of mold on the evaporator core |
A service kit is available through GMSPO in order to correct odors in
the air conditioning system.
A single application of deodorizer GM P/N 12370470 (or
equivalent) removes odors from the air conditioning system. Install a delayed
blower control module in order to prevent the odor from returning. Refer
to the delayed blower control module installation instructions.
- Ensure that the plenum that draws air from the outside is clear
of all debris.
