Hi guys, new here,

I figured I'd pick your brains for ideas. I have a 96, Non-turbo h1,

Now my a/c is not blowing cold (will get looked at shortly) but heater works fine (for an h1)

I find lately my rear fan blows hot all the time , the front heater will blow outside cool

Nicely but my back fan seems to be always at full out hot air, I thought they were on the same gauge for temp.

I have the upgraded heater . I'm just trying to figure why would be on hot all the time when I turn on the fan, there has been time it blew cool room temp to warm air, but now all I get is hot, any ideas what I'd look at?

Thanks

You have a problem with the hot water valve or vaccum controls that operate the valve

the front heater has a temp door the rear does not. hense the temp differance

this is possibly why your AC is not cold
