Heater help

[ihiryu]

Okay, so I've been doing some digging around on the forums and the FSM. Pretty my car has factory A/C, I've taken a look at the vacuum lines in the engine bay, are good, has vacuum at the canister.

 

I look inside my car, and check the cables as best as I can, and I see they are hooked up; same with the vacuums.

 

So what I did was turned on my car, set the blower on max, and moved the valve to heat. There isn't any air moving over the heater core, so I'm pretty sure that's why I don't have heat. Later today when I'll drive it, I'll check to see if the core itself gets hot or not.

 

Anyone have any ideas?

What about the other knob? AC Vent Fresh, etc. It matters.

Fresh, REC seems to work, defrost moves closes the ports on the side of the heater core. So everything works, I don't know what BI Level does though

There is a whole series of diagrams in the FSM AC section that show how everything works. Sounds like your water cock might be jammed though. Moving the lever to heat should open the valve and let water flow. Are you sure that the hoses to the heater core from the engine are connected? They get blocked or bypassed by owners quite often when the core starts to leak.

Yeah they are hooked up, the two in the firewall are there. I went out and touched the hoses from the firewall (on the inside) and they are luke warm at best. Car warms up rather normally, so I'm sure there's a thermostat in there.
