Default wheel bearing and heater.

Hello, im new to the forum, and i am from Norway, and i are very bad in English.
google translator .. <3 Here in Norway there is no help or tips to get.

I have a 1998 Astro Safari AWD vortec. and when I run, there comes a trundled sound. sound is higher when the move increases. may sound like a wheel bearing that has been dead. can this be true?

And heating apparatus. in Norway it is important to warm the air ..
It sounds like the fan has daughters down the heater and lies and spins the runt. sounds downright freaking out when I turn it on .. but it comes hot air out. any idea?
looked a little after the fan, and it looked like I had to remove right front screen and get out the fan. or is it a different way and get out the fan on?

And more heat apparatus.
rear heater, it just blows cold air. shell it do it? or is it a tap or valve somewhere?

Very sorry my bad english, thanks for the help if anyone understands me.

Well, let's give this a try.

Yes, the wheel bearings can wear out. Not too difficult to replace. Is it coming from the front or back?

The bearings on the fan can wear out as well. Usually the fan assembly is replaced as a unit. It's located under the hood on the passenger side.

Rear heat, believe the controls are vacuum operated and suspect a vacuum hose has come undone or broken.

Lagrene på viften kan slites ut også. Vanligvis viften forsamlingen er erstattet som en enhet. Det er plassert under panseret på passasjersiden.

Bak varme, tror kontrollene vakuum operert og mistenker en vakuum slange har kommet ugjort eller ødelagt.
