Testing Delayed Blower Motor Control Module
1996 Saturn SC2 L4-1.9L DOHC VIN 7SECTION Testing Delayed Blower Motor Control Module
A full functional check of the delayed blower motor control module is required to assure that all electrical connections are connected properly and it is functioning as designed.
1. Locate the GRN wire at cavity H of the delayed blower motor control module and insert a metri-pack 280 series male test adapter into cavity H until contact is made with ORN wire terminal in the delayed blower motor control module pigtail connector.
IMPORTANT:
Do not disconnect the jumper harness connector from the delayed blower motor control module pigtail connector or system test will not function.
2. Start engine and turn On A/C and verify that compressor clutch engages. With clutch engaged, apply battery voltage to the test adapter installed in step 1 above.
After 30 seconds, turn the ignition Off with voltage still applied to the test adapter. Approximately 10 seconds after the ignition is turned Off, the blower motor will run for one second if the delayed blower motor control module is wired correctly.
3. Disconnect voltage to the test adapter and remove adapter from connector.
4. If the delayed blower motor control module runs for one second, go back to installation procedures and install parts removed from vehicle. If the delayed blower motor control module does not run for one second, go back to installation procedures and check all wiring connections. Refer to "Delayed Blower Motor Control Module Diagnosis" in this bulletin if functional check is not passed.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
