heater problem..... cold like heck...

mrnickleye · 01-18-2007, 06:16 AM

the heater core is inside, behind the glove box. so if it were to leak, you would have coolant on the passenger floor. you must have a leak at engine or hose under the hood to get the smoke.

the air should come out each area you place it in. ie: defrost, floor, vents. hot or cold won't matter. the temp is controlled by the temp up/down control.

it sends none, or more & more air thru the heater core as the temp setting is raised.

if air comes out good in high fan when temp is on cold (like 65*), but not when setting is on 85*, then there is some thing blocking the air flow thru the heater core. dirt/lint?

yes i do know that the heater core is under the passenger side floor and underneath or on the back of the glove department...

i turn it to max heat and max blow... and mid heat and max blow and mid heat and mid dlow... it still the same... i dont gain any heat...
like you said... i sure gain more hot air when i turn to 85* and doesnt matter high or low air... i still dont gain anything...

to me i think i either have a bad heater core hose or either mly heater core...
but i'm not sure...

hey uh... what about if my water hose is bad... example one of the hose is blocking or if there is something inside the hose and it clock aka stuck inside the holes for stoping the water coming from the head of the engine to the heater core..

can that be a problem too...

sorry for my poor grammer...

The hoses won't be plugged, but the valve on the firewall may not be opening all the way. Pull the vacuum hose off the little solenoid and put it directly on the water control valve.

This will give you full valve opening.

make sure there is vacuum at that little vacuum hose. when I got my car it was not hooked up on the other end to the intake manifold, so the heater core was not getting water.

huh? i wonder which vacuum hose and wich solenoid... and where is it located at...

i didnt remember seen a solenoid and a little vacuum hose on the heater core... you got picture of that...

if you do that will be great...

the valve on the firewall (under the hood, passenger side, heater hose from engine goes in one end, and other goes into car to heater core) may not be opening all the way.

Just read and do A. & B. Don't bother with doing C.

You do NOT need to replace a bad solenoid, just by-pass it and plug the vacuum line directly into the water valve.

The system 'normally' keeps the valve open (water flowing), all the time, except when the temp is set to 65*.
