no heat but I rigged it to work
Hello all, I have a 1996 ssei that has intermittent heat. The heat works & works great, about 10% of the time, then the rest it only blows cold air. Ice cold below zero air as I live & shiver my butt off in Iowa. Sometimes after I restart the car it works, but usually not. I looked at other posts with great pics & all about the vacuum block with the violet hose & how the inside of that block gets aged hoses, mine all look GREAT. That block does have an open connection with no loose hose around to attach to it, so I put a vacuum plug over the end of it just in case. After I removed the glove box liner, there was still no way to see the actuator arm at all. I used an angle grinder to cut out a healthy slot from that steel part, without damaging anything but my right ear when hot slag bounced into it. You should have heard the noises I made. My nephews who were holding the light are still laughing now I am sure. The actuator arm moves to allow the warm stuff to circulate, then it goes the other way. Sometimes the climate temp will blink when this happens, sometimes it wont. When I disconnected that arm, the flap made a strong thump to the heat option, and it stays there very well. I have left it like this so I will not freeze my tuckus off any more. Does anyone have any real advice I can use to fix this issue? I don't know if it is tied to the issue that started last spring with my a/c not working also causing my cooling fans not to come on ever -until I put in a switch to turn them on. I would really just like to fix the whole mess at once since it all seems connected somehow. Now, I imagine some of you may ask about these things, so I will clear the air now. I replaced my radiator recently & bled the air out very well, also added new thermostat at that time as insurance. The hoses on both top & bottom (too & from) of the heater core get warm, so it is not clogged at all. I did take pics of the mess, but I can not figure out how to post them here. Someone please help!
