Heater Control Knob

In development

Hand-turned knob on the heater/climate control lever on the dash. Toyota's own OEM catalog designation for the original documented part is "KNOB, HEATER CONTROL LEVER" (55905-12060, mfr note "W(BOOST VENTILATOR)"), confirmed via toyotapartsdeal.com's dedicated OEM part page -- its own fitment table explicitly lists chassis codes MA61L-BLMQFA/K and MA61L-BLPQFA/K (1982-1985 Celica GT/GTS/ST/Supra, A60 generation). That part is marked "Replaced By: 55905-12070" ("Control Knob Sub-Assembly"), whose own dedicated page's fitment table likewise explicitly lists the same MA61L codes under "1982-1989 Toyota Celica: GT, GTS, ST, Supra, Turbo 4WD, Turbo All Trac". epc-data.com (primary reference drawing source) returned HTTP 429 this session before its MA61 heater-control diagram group could be located.

The paper trail: superseded to 55905-12070
