Cadillac Deville Window Regulator

Good Cadillac Deville Window Regulator Gone Bad

The window regulator of a vehicle allows you to lower or raise the windows at ease and at your own convenience. If this gets broken, it will negatively affect the performance of the glass windows, making it hard for you to control them. In the long run, it's inevitable for the regulator to get damaged, especially when proper maintenance is not done. Here are some signs and symptoms to tell if the Cadillac Deville window regulator has gone from good to bad.

Glass windows that refuse to go up and down

One of the most obvious indications to know that there's something wrong with the window regulator is if the glass windows refuse to go up and down whenever you try to work them. If this happens, it's likely that there's a blown fuse or connection break in the regulator motor. You can just simply adjust this without necessarily replacing it. Take note that if most of the windows don't function, then replacing the regulator motor may be required.

Odd noises

As you control the windows of your vehicle, try to listen to the sounds that it makes. If you hear different noises, then it's a sign that the window regulator is about to go south. Try to move the raised windows and assess if you hear the regulator motor sound; if you do, then that's because of a motor that's out of alignment. If not, you'll have to get the whole window regulator replaced with a new one.

Stiff movement or rust

Take a good look at the joints of the window regulator if there's rust or stiff movement and if the electrical system is operating as it should. It's possible that the joints could break or corrode, which causes the windows to stop working. You can fix this by taking out the window regulator from the door panel and installing a new one so that it can work properly again.

Damaged wiring harness

Examine the wiring harness from the fuse panel to the switches and from the switches of the window regulator. If there's a broken or short harness, then you'll have to visit a professional mechanic to get this replaced with a new one.

  • Proper Cadillac Deville Window Regulator Maintenance 27 February 2013

    It's important that you maintain the performance of the window regulator on your car; otherwise, raising or lowering the glass windows would definitely be difficult and a hassle for you. It's quite unavoidable for this part to get busted, especially if you don't do proper upkeep. Here are some tips and tricks that you can use to take good care of the Cadillac Deville window regulator.


    Regularly grease the window regulator.

    If you sense that the window regulator is becoming dry, then it's in need of getting greased again. It can be an expensive maintenance tip, but it's important in order for your glass windows to work correctly. It's really simple to do this tip. Remember to clean old oil and grease from the regulator; do this by using a paint brush and carburetor cleaner. You can get white grease from any automotive store. This is what you're going to spray in front and behind the regulator pivot points and motor.


    Lubricate the window channel.

    One of the reasons why the window regulator fails is because the window channel gets dried up. You can use Teflon or silicon spray, depending on your preference, to lubricate the window channel. Do this with the window all the way down and stick the straw into the tip of the spray to apply it directly to the top and sides of the window channel. Raise and lower the glass window a couple of times and clean it right after.


    Clean the window regulator.

    Most people would think that cleaning the window regulator is not possible. If the glass windows start to get sticky, then this is an indication that you'll have to get the regulator cleaned. Just open the door panel carefully and look at the window regulator. It may be dirty due to old grease or oil. Just easily wipe it clean; if it's dry, you can add grease again.


    Fix the window regulator.

    If you discover that the window regulator is faulty and must be fixed, don't hesitate on doing so. Plus, you can always go to a professional mechanic to do the repair for you. If all else fails, then installing a new window regulator will be your best option.
