idk my 97 dosent have hydroboost i would think to check the vac pump too

Oh I suppose thats possible? Its been in the 20's here during the day.. perhaps thats what it is then? I could swear it had a blackish tint to it

Where would the vac pump be located?

its the half of the power steering pump towards the front of the truck.

Actually, 300K *is* a lot. It may have a cummins in it... but it's still a Dodge.

haha THANK you. I just can't say it around dodge people.

I was messing with the truck today. Pretty positive no hydroboost. The pedal feels car-like, and the brakes/powersteering dont intertwine I dont think.

Good. My hydroboost on my psd was a pain in the ass

then yeah you do have a vac pump, someone correct me but i'm almost sure it only runs the brakes.

It doesnt run the hvac or anything?

Vacumn runs the HVAC 4wd actuator as well as the cruise control I think.

Ohhh thats got me wondering. The cruise control doesn't engage (but the light on the wheel will turn on), and I cant control where the heater directs the heat. Sounds like I may have inadvertantly found the solution to 2 other problems here...
Now to track down that scandellous leak!
