9. Pack adhesive into the cartridge without air pockets

to ensure continuous delivery. Put the cartridge in a

caulking gun, and run a bead of adhesive around

the edge of the rear window as shown.

NOTE: Apply the adhesive within thirty minutes

after applying the glass primer.

Make a slightly

thicker bead at

each corner.
10. Use suction cups to hold the rear window over the

opening, align it with the alignment marks made in

step 4, and set it down on the adhesive. Lightly

push on the rear window until its edges are fully

seated on the adhesive all the way around.

NOTE: Do not close or open the doors until the

adhesive is dry.

11. After the adhesive is dry, spray water over the rear

window and check for leaks. Mark leaking areas and

let the rear window dry, then seal with sealant.

NOTE: Let the vehicle stand for at least four hours

after rear window installation. If the vehicle has to

be used within the first four hours, it must be driven

slowly.

12. Connect the rear defogger sub-harness and ground

cable/antenna lead, then install the grommets.

13. Reinstall all remaining removed parts.ProCarManuals.com

Switch Replacement (cont'd)
Rear Window Defogger

5. Disconnect the 18P and 10P connectors.

CAUTION: Be careful not to damage the SRS wire

harness.

6. Remove the six screws, then remove the rear win-

dow defogger-light switch assembly.

7. If necessary, replace the rear window defogger

switch bulbs.ProCarManuals.com

Rear Window Defogger

Function Test

CAUTION: Be careful not to scratch or damage the

defogger wires with the tester probe.

Check for voltage between the positive terminal

and body ground with the ignition switch and the

defogger switch ON. There should be battery

voltage.

If there is no voltage, check for:

— Faulty defogger relay.

— An open in the BLK/GRN wire.

If there is battery voltage, go to step 2.

POSITIVE TERMINAL

NEGATIVE TERMINAL

2. Disconnect the positive terminal, check for con-

tinuity between the negative terminal and body

ground. If there is no continuity, check for an open

in the defogger ground wire.

3. Reconnect the positive terminal, touch the

voltmeter positive lead to the middle of each defog-

ger wire, and the negative lead to the negative ter-

minal. There should be approximately 6 V with the

ignition switch and the defogger switch ON.

If the voltage is as specified, the defogger wire

is OK.

If there is battery voltage, the defogger wire is

broken on the negative side.

If there is no voltage, the defogger wire is

broken on the positive side.
Defogger Wires Repair

To make an effective repair, the broken section must be

no longer than one inch.

1. Lightly scrub the area around the break with fine

steel wool, then clean it with alcohol.

2. Carefully mask above and below the broken section

with cellophane tape.

OPEN

CELLOPHANE

DEFOGGER WIRE

3. Using a small brush, apply a heavy coat of silver

conductive paint extending about 1/8" on both

sides of the break. Thoroughly mix the paint before

use. Let it dry for thirty minutes.

PAINT

4. Check for proper operation with a voltmeter (it

should read half of battery voltage at the mid-

point).

5. Apply a second coat of paint in the same way. Let it

dry for three hours before removing the tape.ProCarManuals.com
