I have a 86 bronco 2. The engine comes up to temp just fine. Cant seem to get heat outta the heater? Is their a heat control valve or just the blend door? Maybe plugged up heater core? Just replaced the thermo with a 195. Any info would be great.

Thanks

grab the heater hoses when the engine is up to temp, make sure there both hot.one maybe a little hotter than the other. the fan work??

One is alot warmer than the other. Plugged heater core? Is their a heater temp valve? or just the blend baffle?

baffle. maybe the cable come unhooked

Yeah, I'd check the heater core, simple to pull and while you have it out you may also pull the blower motor (also easy) and see where your leak is coming from... As stated in your other post, this could be because of a stopped up drain in your vent system or it's less possible that you have anti-freeze leaking into the vent.. Either way, this is a good time to get it all under control.. Clean out all the debris, check your dash controls, drain etc.....
