TEMPMATIC Functional Test: "Defrost"
90% of the air should be delivered out of defroster outlets, with 10% coming from heater outlets. Any blower speed, except "LO", may be selected immediately. "LO" operation will be delayed until coolant reaches 120°F. Temperature may be regulated by lower control lever.
NOTE:
In "OFF", "VENT", and "HEATER", heated air can be obtained by moving the temperature lever to the right, without compressor operation.
