Hello Bob and Ken,

I just found this site and I think it is great. I hope you can help me out!

I have a 1995 Plymouth Voyager. It has about 120,000 miles on it. It is the short van, no luxuries like power windows, or even cruize control. It is the basic, you get nothing model, with the white paint that peels. It is a V-6.

I must be cursed when it comes to heater trouble. Two winters of COLD. The heater only works if I am driving. The faster I go the warmer the air is.

So I warm the van up in the morning and when I get in, the engine is at it's "warm" temp, but the heater air is not, it blows out cold air. When I drive about 55 it blows out decent warm air. I have had the dash pulled out and vents and vaccumms have been checked. I recently got the van tuned up as well.

Do you know what the problem could be?

Thanks so much!

I'm just the janitor, Bob and Ken are at Hidden Beach resort in Mexico.

Is your coolant full?
If so is the flow restricted through the heater core?

I thought the van had 120,000 but it has 128,000 miles on it. Guess I haven't been paying attention to well to that.

This morning it was only about 55 degrees and I couldn't get the hot air to blow out at all until I was going 70 mph. Just cold air blows out. It also is very loud down in the floor on the passenger side when I have the heater on high. There is also a slight breeze that comes in on the passenger side floor.

I know the coolant is full. How do I get the air flow checked. Since there is cold air coming out does that mean it is restricted? I am a do it yourself-er type person. Well, have my husband or my dad do it themselves I guess I should say : :wink:

Thanks

The loud noise you hear is probably the blower motor going bad or the fan on the motor. That will affect the volume of air coming at you, but not the temperature. I assume the air flow is good?

As opposed to checking the COOLANT flow not air, you can pull off the heater hoses at the heater core and run water through it with a hose, not high pressure, then reverse the direction.

Also possible the thermostat is stuck open.
