Check for a vacuum leak somewhere

It should have a snap ring on the top of it take that off

Remove the gearbox is the only answer

The challenge on most GM V6s is to rotate the engine to get to the back side of the engine. Usually there is an engine mount on the left front (Looking at the car) to lossen this allows you to rotate the engin forward to get to the spark plugs etc.

Disconnect battery (always neg pole/post first) find alternator, loosen belt. disconnect wiring @ alternator. take alternator off. put alternator in place of it put belt on tighten all screws, belt tension screw first.

Remove the bonnet, drain oil and water remove radiator and fan remove all hoses cables and wiring attached to the engine. take weight of engine with a floor crane support the transmission .uncouple transmission from engine remove engine mount bolts , take a little more weight with the crane and slide engine clear of transmission , lift clear of car and slide crane clear to engine stand.

Under the middle of the car towards the driver side. If you look under the driver side passenger door you should be able to see the vent lines going to it.

This is a really common problem with these Auroras. I just let mine go. If you HAVE to fix it or really WANT to, you will need to replace the solenoids. These are roughly $200.00/ea. There are two of them.

Check that the temperature control in the door is connected. Check the temperature sensor under the glove box.

These should be under $100.00, but there are at least 3 of them, and it's really not easy to tell which if any are bad. I would say, too difficult for a novice.

Check fuses first. Next look at the connections/wiring starting with the drivers side door. Drivers side is the master, so if it doesn't work, usually the remaining doors will not work either.

If the motors are not running, I would start with the window switches, then look at the connections inside the door panels. Body control module is not a common failure point for this issue.

Check the ground connection where it connects to the frame on the passenger rear of the car. Also check the fuel relay in the fuse panel under the rear seat.

Possibly you are over-charging the battery. You will need to check the battery voltage with the car running - you should get 13.7v to 15.1v. Anything above 15.1v means the regulator is bad and you are overcharging.

check and replace if needed,spark plugs,air filter,make sure brakes are not dragging,hook up a system analyzer check the codes

Look for a vacuum line off or leaking start in the engine compartment than work your way under dash usually in engine compartment but could be under dash usually passenger side or on the back of control switch on dash.

there is only two connections on your starter, two red power feeds(large lug hole) and a purple wire(to small post "S") If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541

test voltage when running if over 14.8 volts then the regulator in the replacement alt is no good.

I am guessing its under the hood.. it sounds like a vacuum hose is partly kinked or plugged, or the butterfly on the throttle body is dirty. and will make a buzz like noise at higher rpm.

find the leak first then get the right amount of fluid in it then see what it does
