That's the default mode. You have a vacuum leak. First be sure you have vacuum supplied to the line going through the firewall on the passengers side. If you don't the problem is under the hood. If you do, it's under the dash.

Do you know if and where i can get the routing for the vacuum hoses?(i noticed some small hoses broken and reconnected them but, not sure if i put it on the right places,my parking brake is not releasing also)Its a 96 eldorado northstart of course.

Here is the routing of the vacuum hoses that impact the HVAC

The one that does down and connects to the black canister under the RF headlight connects directly to the canister, there are no hoses, its nylon tubing.

There is a T at the top, and a one way check valve, I would just make sure that all those hoses are connected and there are no cracks. The next step would be to get under the dash on the passenger side and see how the hose looks that comes through the firewall, where it connects

You can use a hand held vacuum pump with gage on it to test the integrity of the hoses going to the tank, you can buy one at sears

I would check for vacuum at the connector under the dash.

Does your parking brake release when the selector is placed in DRIVE?

No i have to release my parking brake manually...

Well the parking brake is part of the vacuum system

Do you have a vacuum gage?, if you do, hook it up at various locations on that vacuum line to check for vacuum.

Try sears or one of the popular auto parts shops, its not expensive, you are simply looking for a vacuum gage
