Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 2005condenstion on windows
My Geo metro has had, for the last week or so since it's been very cold out, water/condensation on the inside of the windows, making it difficult to see; it's hard to even wipe it all off cleanly. And as of yesterday I've noticed there is smoke/steam(?) coming ever so slightly from the vent on top of the dashboard. I have a feeling it's related...so what is it, and what can be done? > My Geo metro has had, for the last week or so since it's been very cold > out, water/condensation on the inside of the windows, making it > difficult to see; it's hard to even wipe it all off cleanly.

For the condensation ... - drive with a window open a bit for a while. - stop exhaling all that hot moist air on the inside surface of the windows. :) - turn on the heater defroster to blow warm air the windows so they aren't so cold. Don't know about the vent, sorry. gregf@kcls.org writes in article <1134080419.383053.215110@g47g2000cwa.googlegroups.com> dated 8 Dec 2005 14:20:19 -0800: >My Geo metro has had, for the last week or so since it's been very cold >out, water/condensation on the inside of the windows, making it >difficult to see; it's hard to even wipe it all off cleanly.

It could be the beginning of a heater core leak. Does it smell like antifreeze when you run the heater? -- spud_demon -at- thundermaker.net The above may not (yet) represent the opinions of my employer. One of two things comes to my mind. First the carpets are wet. If you dry them, the fogging will go away. You will need heat on fresh air and likely to drive with a window open to help dry things out or if the carpets are really soaked, fix the hole in the floor or get mats that grab the snow and take a hair dryer to them.... Second is the heater core leaking. If that, you will get a sweet antifreeze smell and the rad will be going down on fluid. You might get away with some radiator stop leak to fix that or it could just plug up the works so you have no heat and have to change the heater core anyway.

It's very strange. The mats are not wet. I don't think it has any heater problem (it does heat up eventually, but like any old car it can take a while), and there is no smell. I've wiped it all off really good with paper towels, but after driving for a while it still comes back. I do realize now that it started happening after I got it back from a garage, to have the fuel pump fixed and a tune up. I guess I could call them. > One of two things comes to my mind. > [quoted text clipped - 23 lines] > > from the vent on top of the dashboard.

SignaturePaul Hovnanian mailto:Paul@Hovnanian.com ------------------------------------------------------------------ Why are so many towns named after water towers? Keep a close watch on your coolant level just in case the heater core is leaking. By the way, there is no good reason an old car should be short on heating. A well maintained cooling system with functional blend doors will produce heat very well. OK, according to the garage, it was the heater core. $575 later, after driving it 5 minutes, the back windows have water on them again. Now I'm really confused. Is this how it works- in the winter cars get water on the inside of the windows and as long as your heater core is working this should go away with the defrost on in 20 minutes or more? How does the water get there in the first place? Now I can't seem to remember what is or isn't normal. I'm losing my money and my mind. The front windows got a bit foggy which then went away with the defrost on full blast for a while. > Keep a close watch on your coolant level just in case the heater core > is leaking. > By the way, there is no good reason an old car should be short on > heating.

The defroster heats that area and vaporizes the water back into the air. The rear window is usually harder to keep clear because it is farther away from the heater and the air cools off. Also since you had a coolant leak the carpet padding is probably damp as well which means you have even more water in the car than normal. This makes the problem worse, as well as rotting the carpet and floor in the vehicle. Water enters the vehicle in the air, when it rains water does get by some seals and into the doors and other panels as you drive. This is supposed to drain out but if the drain holes are blocked it can get enough water to get into the interior of the vehicle. Then when you get in/out that big open hole for the door lets water and snow in plus the snow on your feet. It all adds up.

It is better than it was- by the time I took it in last friday all the windows were so bad it was dangerous to drive and full blast defrost was doing nothing at all. I was just dissappointed to see all the windows clear and then so quickly have the backs ones get wet so soon again. > OK, according to the garage, it was the heater core. $575 later, after > driving it 5 minutes, the back windows have water on them again.

Breathing. Try not to breathe. >My Geo metro has had, for the last week or so since it's been very cold >out, water/condensation on the inside of the windows, making it >difficult to see; it's hard to even wipe it all off cleanly.

Make sure you don't have the recirculate air button on. -------------- Alex |
