The BMW 645ci and 650i models produced between 2004 and 2007 came with a power window system for their front seats. If you are in need of a new master power window switch for the front left seat, here are some pros and cons to consider before making a purchase.

Pros:

1. Convenience: A power window switch makes it easier to operate the window with just the press of a button, especially when driving or parking in tight spaces.

2. Comfort: Power windows allow for precise positioning of the window, ensuring optimal comfort for the driver and passengers.

3. Durability: BMW is known for its high-quality parts, and a new power window switch from the original equipment manufacturer (OEM) is likely to last longer than aftermarket alternatives.

Cons:

1. Cost: Replacing a power window switch can be an expensive repair, especially when dealing with a luxury vehicle like a BMW.

2. Labor costs: If you are not comfortable installing the switch yourself, you will need to pay for professional labor costs.

3. Availability: Depending on the specific model year and availability, it may take some time to source and receive the replacement part.

If the convenience and comfort of power windows are important to you, and you have the means to cover the cost, then purchasing a new OEM switch may be the best option.
