Seat belt warning light & chime & intermittent wiper issues

The seat belt I will look up the wiring and post it if you post your email you will get a better quality copy sent to you. The wiper issue csn also be the multifunction switch. When I get to my book I will post testing proceedures.

Is your airbag light lit? There is a bulletin for corrosion of the connectors for seat belt prtensioner under the driver and passenger seats. Let me know if air bag light stays on.

RESTRAINTS CONTROL MODULE (RCM)
RCM contains microcomputer, which monitors electrical system components and
connections. RCM performs a system self-check of air bag system internal circuits
every time ignition switch is turned to RUN position. RCM also energizes AIR BAG
warning light during initial system self-check and whenever a fault is detected. Faults
are stored in RCM memory and translated into flash codes, which are displayed
through AIR BAG warning light. RCM also communicates through Data Link
Connector (DLC) current and historical Diagnostic Trouble Codes (DTCs).
If a system fault exists and AIR BAG warning light is malfunctioning, RCM signals
Generic Electronic Module (GEM) to activate a chime, indicating need for service.
TEST Y: NO COMMUNICATION WITH RCM
Description
Restraints Control Module (RCM) communicates with scan tool using International
Standard Organization (ISO) 9141 communication mode through Data Link Connector
(DLC).
Possible Causes
A no communication condition could be caused by damaged wiring, terminals or
connectors, damaged DLC, damaged scan tool or RCM internal fault.
1. Check RCM connector & pin No. 5 for damage
Turn ignition switch to OFF position. Disable air bag system. See DISABLING
SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Access
RCM and disconnect harness connector. See RESTRAINTS CONTROL
MODULE (RCM) under REMOVAL & INSTALLATION. Inspect RCM
connector, terminal No. 5 (Light Blue/White wire), component side and harness
side, for damage. See Fig. 12 & Fig. 14. If module pin and module harness
connector terminal No. 5 are okay, go to next step. If module pin and module
harness connector terminal No. 5 are damaged, repair/replace as necessary.
Reconnect air bag system. Retest communication with RCM. Activate air bag
system. See ACTIVATING SYSTEM under DISABLING & ACTIVATING
AIR BAG SYSTEM. Perform system operation check. See SYSTEM
OPERATION CHECK. Clear all DTCs. See CLEARING FAULT CODES
under DIAGNOSTICS.
2. Check DLC for damage
Inspect Data Link Connector (DLC) and DLC connector terminal No. 7 (Light
Blue/White wire) for damage. See Fig. 16. DLC is located under left side of
instrument panel. If DLC connector and DLC connector terminal No. 7 (Light
Blue/White wire) is okay, go to next step. If DLC connector and DLC connector
terminal No. 7 (Light Blue/White wire) is damaged, repair/replace as necessary.
Retest communication with RCM. Reconnect air bag system. Activate air bag
system. Perform system operation check. Clear all DTCs.
3. Check circuit for short to battery
Measure voltage between ground and DLC connector terminal No. 7 (Light
Blue/White wire). If any voltage is present, repair short to battery voltage in
Light Blue/White wire. Retest communication with RCM. Reconnect air bag
system. Activate air bag system. Perform system operation check. Clear all
DTCs. If no voltage is present, go to next step.
4. Check circuit for open
Measure resistance of Light Blue/White wire between RCM connector terminal
No. 5 and DLC connector terminal No. 7. See Fig. 12 & Fig. 16. If resistance is
less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair open in
Light Blue/White wire. Retest communication with RCM. Reconnect air bag
system. Activate air bag system. Perform system operation check. Clear all
DTCs.
5. Check circuit for short to ground
Measure resistance between ground and DLC connector terminal No. 7 (Light
Blue/White wire). If resistance is less than 10 k/ohms, repair short to ground in
Light Blue/White wire. Retest communication with RCM. Reconnect air bag
system. Activate air bag system. Perform system operation check. Clear all
DTCs. If resistance is more than 10 k/ohms, replace RCM. Retest communication
with RCM. Reconnect air bag system. Activate air bag system. Perform system
operation check. Clear all DTCs.

Your Restraint control module controls the light and chime, not the GEM, Check pin 5 on the RCM, It's located on the tranny tunnel under the dash. Pins are shown in the pictures.

And yes get the codes read, both PCM and ABS

First the MIL(Malfunction indicator lamp) will return if cades are stored, second Autozone reads them for free, but not the ABS codes.
If you will post your email, I will send you the wiring diagram, and yes the chime and drivers bucke are the two wires that go into the RCM and GEM. If you want the diagram I NEED your email!

Ok the gem stores B codes mostly so generic scanners don't work. I will email the wiring diagram when I get home tonite.

Safety Belt
The safety belt warning indicator is controlled through the Generic Electronic Module
(GEM). When the ignition key is turned on the RUN or START position during the
first sixty-one seconds +/- one second, the indicator illuminates if the safety belt
remains unbuckled.
2 PDF's on way to your email, one for troubleshooting the lamp, the other is the wirind diagram for the cluster.

I strongly suggest a code scan, B code(s) must be stored, and will tell you what the problem is.
