PROCEDURE

1. INSPECT NO. 1 HEATER CONTROL SUB-ASSEMBLY

   1. Measure the resistance.

      1. 

         *a	Component without harness connected (No. 1 Heater Control Sub-assembly)
         *b	Recirculation/fresh Switch

         Remove the No. 1 heater control sub-assembly.

      2. Measure the resistance according to the value(s) in the table below.

         Standard Resistance

         Tester Connection	Condition	Specified Condition
         3 (FRS) - 4 (REC)	Recirculation/fresh switch: OFF	Below 1 Ω
         3 (FRS) - 4 (REC)	Recirculation/fresh switch: ON	10 kΩ or higher
         5 (LED+) - 4 (REC)	Recirculation/fresh switch: OFF	10 kΩ or higher
         5 (LED+) - 4 (REC)	Recirculation/fresh switch: ON	Below 1 Ω

         • If the result is not as specified, replace the No. 1 heater control sub-assembly.

   2. Check the indicator light.

      1. Turn the recirculation/fresh switch to the on position.

      2. Connect a positive (+) lead from the battery to terminal 2 (A/C+) and negative (-) lead to terminal 4 (REC), and check that the indicator light comes on.

         OK

         The indicator light comes on.

         • If the result is not as specified, replace the No. 1 heater control sub-assembly.

   3. Check that the illumination light.

      1. Connect a positive (+) lead from the battery to terminal 7 (ILL+) and negative (-) lead to terminal 6 (ILL-), and check that the illumination light.

         OK

         The illumination light comes on.

         • If the result is not as specified, replace the bulb.

2. INSPECT NO. 2 HEATER CONTROL SUB-ASSEMBLY

   1. Measure the resistance.

      1. 

         *a	Component without harness connected (No. 2 Heater Control Sub-assembly)
         *b	Rear Window Defogger Switch
         *1	Blower Switch OFF Position
         *2	Blower Switch LO Position
         *3	Blower Switch M1 Position
         *4	Blower Switch M2 Position
         *5	Blower Switch HI Position

         Remove the No. 2 heater control sub-assembly.

      2. Measure the resistance according to the value(s) in the table below.

         Standard Resistance

         Tester Connection	Condition	Specified Condition
         1 (LO), 6 (HI), 8 (M1), 10 (M2) - 5 (E)	Blower switch: OFF	10 kΩ or higher
         1 (LO) - 5 (E)	Blower switch: LO	Below 1 Ω
         1 (LO), 8 (M1) - 5 (E)	Blower switch: LO - M1	Below 1 Ω
         1 (LO), 8 (M1) - 5 (E)	Blower switch: M1	Below 1 Ω
         1 (LO), 8 (M1), 10 (M2) - 5 (E)	Blower switch: M1 - M2	Below 1 Ω
         1 (LO), 10 (M2) - 5 (E)	Blower switch: M2	Below 1 Ω
         1 (LO), 10 (M2), 6 (HI) - 5 (E)	Blower switch: M2 - HI	Below 1 Ω
         1 (LO), 6 (HI) - 5 (E)	Blower switch: HI	Below 1 Ω
         2 (RDEF) - 5 (E)	Rear window defogger switch: OFF	10 kΩ or higher
         2 (RDEF) - 5 (E)	Rear window defogger switch: ON	Below 1 Ω

         • If the result is not as specified, replace the No. 2 heater control sub-assembly.

   2. Check that the rear window defogger switch indicator light.

      1. Connect a positive (+) lead from the battery to terminal 4 (IG+) and the negative (-) lead to terminal 5 (E).

      2. Push the rear window defogger switch in and check that the indicator light.

         OK

         The indicator light comes on.

         If the result is not as specified, replace the No. 2 heater control sub-assembly.

   3. Check that the illumination light.

      1. Connect a positive (+) lead from the battery to terminal 9 (ILL+) and negative (-) lead to terminal 7 (ILL-), and check that the illumination light.

         OK

         The illumination light comes on.

         • If the result is not as specified, replace the bulb.

3. INSPECT NO. 3 HEATER CONTROL SUB-ASSEMBLY

   1. Measure the resistance.

      1. 

         *A	w/ PTC Heater
         *a	Component without harness connected (No. 3 Heater Control Sub-assembly)
         *b	A/C Switch

         Remove the No. 3 heater control sub-assembly.
