How do you change the windshield wiper blade on a 1976 dodge eldorado motorhome?

There's no such thing as a 1976 Dodge Eldorado motorhome. Dodge did not produce a model called "Eldorado" in 1976, or any year. Eldorado was a Cadillac model. Motorhomes in 1976 were often built on chassis from various manufacturers, including Dodge, but badged and marketed under other names (like Winnebago, Fleetwood, etc.).

To replace your windshield wiper blades, I need to know the make and model of your 1976 motorhome. Once you provide that information, I can give you more specific instructions.

However, the general process for replacing wiper blades is usually similar:

1. Identify the wiper arm type: Most older motorhomes will have a hook-type or a bayonet-type wiper arm. Observe how the blade attaches to the arm.

2. Release the wiper arm: There's usually a button or tab to release the wiper blade from the arm. Sometimes you need to lift or push a small lever. Consult your owner's manual if available. *It's essential to take a picture before detaching anything to help with reassembly.*

3. Remove the old blade: Once the arm is released, the old blade should just pull off.

4. Install the new blade: Align the new blade with the wiper arm and attach it according to the instructions on the new blade's packaging. This usually involves pushing or snapping it into place.

5. Reattach the wiper arm: Reattach the wiper arm to the wiper motor ensuring it is firmly attached.

6. Test the wipers: Turn on your wipers to make sure they work correctly and aren't rubbing against the windshield.

If you can't find instructions in your owner's manual, searching online for "[Your Motorhome Make and Model] wiper blade replacement" should yield helpful results, including videos. You may also want to consult a local auto parts store; they might have information specific to your motorhome's wiper system.
