RainX is great

Comment comment by Anonymous on 25 January 2008

My late model S10 has a problem with that too - even on nice days with only slightly cooler air temps. It was particularly annoying because I have a 4 cylinder and every time I turned the defroster on, the engine's power was greatly reduced (it is designed to automatically turn on the A/C to dry the air with the compressor). I found that Rain-X Anti-Fog works well enough to almost completely eliminate fog. It's instructions call for a reapplication every 30 days, but it's so easy that's no problem. It's not so expensive and usually not hard to find in automotive and department stores (in the US anyway). BTW, if you haven't tried the original Rain-X glass treatment (goes on the outside of the windshield) you're missing out. It causes the rain to bead up on your windshield, and as you drive, the wind blows the drops right off. That's a way cool visual effect and works great (at a moderate speed ... >45 Km/h ~ 30 mph).

Awesome - I had no idea they made a version for inside the car. I also agree that it's a cool visual effect to watch the water beads dance around. Especially on the flat window of a Jeep Wrangler. With Rain-X, I don't even need my windshield wipers.

Although your vehicle is different, you can get around that if you're comfortable taking your dashboard apart and soldering. One of the wires leads to the A/C relay and is activated by either choosing A/C or defrost. If you splice a switch inline with that wire, you can have A/C-less defrost or A/C defrost just by flicking the switch. It's a handy feature on a Jeep because the only way you can get top/bottom air simultaneously is with the A/C selected which is pointless in winter. Having the A/C override switch lets you use the vents however you want in a Wrangler. But it would address giving you more control of your defrost in your S10.
