ONLINE MANUAL/ NO HEAT

[MOON]

I know there is one for the MKII but is there one for the 1JZ-GTE ?? it be really nice,

One more thing , i have automatic heat,a/c, one day the heater just went to cold, then back to heat by it self, now its "stuck" on cold air. any words??

i would just use the 2jz's until you get to the clutch part but even then they are pretty much the same.

on the no heat prob. The climate control valve on your firewall. Underneath of it there is a little level that is supposed actuate with vacuum/ coolant flow. It might have went bad. If you push the little lever upwards and the air gets hotter from your heater, then its your climate control valve. If not then beats me.

I bought that part 2 weeks ago. Perfect fit. Just need to solder on your original Connector.

Thanks, i think it might be the main switch, cuz the air temp door was on the cold side, and the coolant valve was still in the non flow side, for to day i just manuly put to hot air, and took the main vac line and stuk it on the actuater to open the coolant line..ill look further into it soon

I've had problems with the heatercore valve not operating due to a bad vacuum source, but I'm not sure if that's our problem.

Do you have issues with your climate control? Like do the lights sometimes turn off for no reason? ask because the heater controls are prone to bad solder joints just like 1JZ ECUs.

ahh CRAP.. like i said before, one night it just went to cold air all by itself, hmmm, so should i remove the control unit and inspect?? i take it cold air is the "fail safe" for the climate control?

if the valve doesn't get a signal to open, it springs shut.
