Then, the A/C amplifier turns ON the RR-DEF relay built into the power distributor response to the input, thus switching ON the rear defogger. (The deicer and mirror heater also turn at the same time)
HINT: The power distributor is built into the J/B No.2.
- The RR-DEF relay is built into the J/B No.2. For inspection, use the terminals in the J/B No.2.
- If RR-DEF relay is malfunctioning , replace the J/B No.2.
