Buying a GM 85112778 door wiring harness can be a solution if you're experiencing issues with the electrical functions in your GM vehicle's doors. Here are some potential pros and cons to consider before making a purchase:

1. OEM Part: This door wiring harness is an Original Equipment Manufacturer (OEM) part, which means it is manufactured by GM and is designed to fit and function optimally in your vehicle.

2. Diagnostic Aid: If you're having trouble identifying the cause of electrical issues in your vehicle's doors, a new wiring harness can act as a diagnostic aid. If the doors start working properly after installation, it's likely that the fault was with the old harness.

3. Improved Functionality: A new door wiring harness can help restore the functionality of various electrical features, such as power windows, locks, and mirrors.

1. Cost: Replacing a door wiring harness can be an expensive repair, especially if it's not covered under warranty.

2. Labor Intensive: Installing a door wiring harness requires some technical knowledge and experience. If you're not comfortable doing it yourself, you'll need to pay for labor costs.

3. Potential for Unrelated Issues: After installing a new door wiring harness, you might still encounter electrical issues unrelated to the harness itself.

A GM 85112778 door wiring harness can be a worthwhile investment if you're experiencing electrical issues with your vehicle's doors and have exhausted other diagnostic and repair options. However, it comes with a higher cost and potential labor expenses, as well as the possibility of unrelated issues. Before making a purchase, consider the potential benefits and drawbacks and weigh them against the cost and your personal capabilities.

If you're confident in your ability to install the harness yourself, purchasing the GM 85112778 door wiring harness could save you money and potentially help resolve any electrical issues you're experiencing. If not, it may be worth exploring options for having a professional diagnose and repair the issue, as they might be able to identify a less costly solution. Ultimately, the decision depends on your comfort level with the repair and your budget.
