I have a 87 GL-10 4wd 5spd Turbo Wagon.

 

1. Heater worked great before winter set in, now it hardly works in the cold weather here at the 8,000 ft. level.

 

2. Headlights get covered with snow slush so much that I have to stop and wipe them off just so I can see the road. Glass feels cold to the touch when I wipe off the slush.

 

Any ideas to help with these problems?

What exactly about the heater is not working? Not hot air? No fan? Both?

 

No ideas on the headlights...sorry.

heater could be caused by low coolant or electrical gremlins.. more details will help or do a search for the word HEATER and you'll find a lot of recent heater repair threads (tis the season)

 

I'd just chalk up the slushy headlights to old man winter thumbing his nose at you. they're cold to the touch as they're kept nicely chilled by the slush (plus 15 HP!) ... just be glad you're one of those with enough sense TO stop and cleanse them. Maybe get one of those scraper brushes with the glove attached?
