On the 2000-2007 Chevrolet Monte Carlo, the Electronic Brake Control Module (EBCM) mounted on the ABS hydraulic unit is prone to failure due to internal solder joint cracking from vibration and thermal cycling. When it fails, ABS, traction control, and stability control all stop functioning. The brake warning light, ABS light, and traction control light all illuminate.
The EBCM can be sent to a rebuilder for solder repair and reprogramming, which is more affordable than dealer replacement. Alternatively, replace the ABS modulator assembly. After replacement, the module must be programmed to the vehicle VIN. Bleeding the ABS system requires a scan tool to cycle the pump and valves.

On the 2000-2007 Chevrolet Monte Carlo, the cable-driven power window regulators are a common failure point, with the cable fraying or snapping and causing the window to drop into the door. This affects both front and rear windows. The motor may still run but the window will not move or will fall down on its own.
Replace the window regulator assembly. Aftermarket units are widely available and affordable. When reinstalling, lubricate the window tracks with dry silicone spray. The door panel uses plastic clips that break easily — have replacements on hand.
