Top 10 1995 Cadillac DeVille Questions & Answers

There is several ways to see. 1. It could still be the heater core, try blowing air in to IN house, if it comes out the OUT hose strong, its not that. 2. It is posible there is an a pocket in the system. Try bleeding the air hose, that could be it. 3. Take the glove box out, disconnect the air bag CAREFULLY! Start the car, And turn the heat all the way up, then all the way down. U should see a arm move back and forth. MAke sure it goes ALL the way shut, and open. 4. It could be that the doors in the dash don't work. I'm not sure how to do this. Hope the other work!!

If so,
When you turn the key to the "run" position (do not crank) do you here the fuel pump run for 2 - 3 seconds?
Let me know.

did you see the yellow wire that they cut into? you have to reconnect that wire. there should be a relay they connected inline to it.

So I'm guessing that when you put it in reverse and it won't move. If you put it in 1st it moves but won't shift to 2nd? And it rattles. And since you have a 4.9 in it the transmission is a 4T60E. I am going to guess that you broke the reverse reaction shell in the transmission.

The location of the starter is as per the car engine.If its 4.5 liter then starter is located on front bottom of the engine.And if its 4.6 liter engine then starter is located under the intake manifold. And On the 4.9 liter the starter is located on the bottom side of the engine. ------------ This will help.Thanks.Helpmech.

The ebrake releases automaticaly when you put it into drive, if the brake doesnt release when in drive then the vacuum release valve may be bad but theres an arm to release in manually, look under the dash where the e brake pedal is and on the side of the braket for the ebrake pedal is a small arm that will release it, good luck hope this helps,
