heater core has probably crapped out or a heater hose broke...can you smell antifreeze?

nope, no smelling of antifreez its just smoke comeing out of the vents and the windows smoke up really bad to where i cant see out them...


Thanks..

You will start smelling it...........................

Lucky for you, they are easy to change in these cars. You change it under the hood, not under the dash.

Alright Thanks alot poncho.. Might you know around about how much a heater core costs??

 

[poncho62]

usually about 80 bucks........................I usually take them out 1st. If it is leaking around the inlet pipe, it can be soldered.

There's a coil resistor on the heater box somewhere before the fan. If you can, try to get in there and make sure you don't have a pile of leaves in the ducting that are smoldering.

If it's smoke and not steam, I'd hate to see your ride go up in flames. Sounds like steam from your description, though, and poncho has you covered.

Pressure test it, you will have coolant run out of the heater box.
Fix it before it completely blows out in side the car.

I also had a very similar problem in my 96 explorer. In my case it was something along the line of the climate control module. Everytime I turned the fan on it blew smoke out the vents. Turned out the module was shorted out. So, everytime I turned the fan on it started fryin again. It could be that, if you have climate control. Jay.
