hey guys..thought i would start a new thread with my current issue....
im not having any hot air coming out of my vents...all cool...no matter how hot the engine. so when i bought the car i noticed at one point it has leaked some kinda a coolant/refrigerant on my carpet on passenger side...right under my heater core/evaporator....since i have a factory AC car my heater core is attached to the AC thingy....
in a previous post someone had mentioned that before i go and take out half my dash and replace the heater core that it may have a bad heater bypass valve...and to check my heat in the hoses under the hood and see what is going on. so i worked on this a little yesterday and what i found out is kind of head scratching... the little hose that go's from the water pump to the intake is buring hot(as it should be), but the hose from the water pump to the firewall is not warm at all, cool to the touch, the hose from the intake to the firewall is not warm at all, cool to the touch...very strange..so if i grab both hoses say in the area over my valve cover before it go's into the bypass valve in my firewall, both are cool as can be like the engine hasnt even been ran at all....
all this was after about an hour drive yesterday afternoon, so the car was good and hot for sure to operating temperature...i did all this checking while car was running also, and still no heat, no hoses warm to the touch etc....very strange...so i started running possibilites thru my head???
1. is the hoses hooked up wrong(it has mostly new hoses this year)
2. is my water pump not working?(car does not over heat and no seapage from pump)
3. is my thermostat stuck or bad?(still think my car would overheat if this the case???
4. does it need a bypass valve and a heater core both and then things would work properly???
keep in mind my AC worked earlier this year for about 3-4 hours then it lost its refrigerant, so im wondering if replacing the pieces under the dash if that would cure both my problems of AC and heat back to working normally. here is a couple of pics of how things are run under my hood....no comments on how dirty it is please, i havent gotten to that part of the car yet....:idea1:
thoughts? ideas? am i screwed? :icon_hang:
