Default No Heat!
I have no heat. No effect when temp is adjusted. Does anyone know the servo part # for the heater? Lexus says 4 are required. Is that correct? Or is there just one?

TIA,

Scott

Not an answer to your question, but did you check for low coolant? (by removing the radiator cap on cold engine, not by checking overflow bottle)?

Rpms drop around 2k rpm then shoot back up. Also does this after letting of the gas.
