PRINTED HEATER LINES CHECK
 |
1.Run engine at 2,000 r/min. Check heater element with battery at full. 2.Turn "ON" rear window defogger switch. Measure heater element voltage with circuit tester at rear window glass centre A. Condition is good if it indicates about six volts. |
 |
3.If 12 volts is indicated at A, there is a break in the negative terminals from A. Move test bar slowly to negative terminal to detect where voltage changes suddenly (0 volts). 4.If 0 volts is indicated at A, there is a break in the positive terminals from A. Defect where the voltage changes suddenly (12 volts) in the same method described above. 5.If a malfunction such as open circuit occurs, replace the rear window glass <vehicles without rear panel power window> or rear slide window glass <vehicles with rear panel power window>. (Refer to GROUP 42, Rear window glass  <rear window glass>, Rear panel power window <rear slide window glass>.) |
