T AUDIO Symptom: Some speakers do not operate 1 Possible cause Damaged speaker Damaged audio unit Damaged DIN cord Open or short circuit in wiring harness Poor connection of connector Open or short circuit in DIN cord 45UOTX-260 Step 1 1. Turn the ignition switch to ACC. 2. Turn the audio system power to ON. Play a recorded tape and set the volume at an appropriate level. 3. Verify speaker operation with the balance, treble, bass, and fader knobs in the positions indicated in Table 1. 4. If not as specified in Table 1, refer to Table 2 and continue troubleshooting at the step corresponding to the faulty speaker. 35UOTX-082 Table 1 1 Speaker Balance I Treble I Left door (woofer) I Right I ( Right door (woofer) I I Left door (tweeter) I Right I Right door (tweeter) Right Driver-side left headrest Right .

TROUBLESHOOTING u TROUBLESHOOTING GUIDE I Symptom Blower motor does not operate Reference page Below Magnetic clutch does not operate I U-7 Condenser fan does not operate e Symptom: Blower motor does not operate I U-9 Insufficient cooling No cooling Intermittent cooling Normal operation of blower motor Blower motor speed is controlled by the fan switch and a resistor in the blower unit. When the fan switch L is in the OFF position, the motor ground circuit is open and the blower motor does not operate. When the switch is in the first (Low) position, current flow from the blower motor is restricted by the three resis- tors in the resistor, and the blower motor turns at low speed. Changing the fan switch to the second (Mid), third (high), or fourth (Super-high) position causes the cir- cuit resistance to decrease, and the blower motor speed becomes correspondingly faster.

PLASTIC BODY PARTS L 5. Apply repairing filler A - A' B - B' Section Repair filler 7 C-C' / D - D' Section The repair filler is a two-part type filler composed of a main agent and a stiffening agent, and has the same flexibility as the urethane when hardened. In the case of air drying [18"C (65"F)], the part may be sanded after approx. 2 hrs. In the case of heat drying [50°C (122"F)], the part may be sanded after approx. 40 min. 6. Air dry or heat dry. Dry the applied repair filler completely. Drying time 7. After the repair filler has completely dried, and the repaired part with #I 20, #I80 and #240 sandpaper, respectively, to make it smooth. The effected part must not exceed 80°C (1 76"F), 120 or it may be deformed. ; go .- 3 - C 60 0 .- C h 3 0 30 0 A - A' B - B' Section , * n, --- - - : - - -- I I I ----- 1 -- - I I I --- --: --- I I I , - - - - - - - - - - -----; ----- L ----I I I I I I I I , I I I I - I 8 I I D - D' Section , 10 20 30 40 50 (50) (68) (86) (104) (122) Temperature "C (OF) Note If the repaired part is made concave, apply extra repair filler.
