I ended up replacing the complete air dryer.

That will do it, maybe replace the dryer cartridge too. 

Where would that be located on the truck?

So figured it out yesterday. The outcome is I better start draining my tanks more often. Rookie mistake I guess. The secondary tank had an enormous amount of water in it after it unfroze.

Yes, I put it in the shop yesterday so it would defrost. I'm going to check it out after lunch. I just needed some pointers to start with. Thanks. I will update.

67 RModel, I will check that out today. Thanks.

Hey guys, I have an 2001 Rd 688. Started it up today and I'm only building about 90 psi on the guage, but the low air buzzer isn't building any pressure at all. The green needle on the guage reads about 90psi. The orange needle reads 0 psi and obviously the buzzer is going off. I'm in Michigan, could it be frozen? Where do I start. I normally would call my buddy, but unfortunately Covid took him way to soon......

The lever on the temperature control seems to be stuck. You can put pressure on it to move but it springs back. Any Ideas?

Is this steer axle still for sale?

Hello everyone. New member here. I have a 2000 RD688. Totally new to big trucks. First off I'm trying to figure out which light on the dash is the ABS light. Its my understanding that this light should come on for a few seconds at start up. Problem is I not really sure where the light is located... Please help. RD6michigan....
