There is no way to diagnose this without the use of a scanner that can display live data and fault codes from the HVAC electronics. Very often a MB will lose the cold air and the led on the ac turn on button will remain illuminated at all times which indicates a problem already. Sometimes just erasing HVAC codes can get the system working normal again (for a short time) and sometimes not. There are so many sensors and components that the odds of you being able to decide what you should replace and then be correct is slim to none. You will throw parts at it and will not likely be successful. There are calibrations and software changes as well. I am a big proponent of the DIY trade but this one, IMHO, skip it. Bring to MB experienced tech.

There are no auto parts sold directly from AutoMD. Check the many on-line auto parts sources, such as; www.autopartswarehouse, www.carpartswarehouse.com, or www.rockauto.com for the replacement parts.

Several possibilities; faulty turn signal lever or switch, faulty turn signal flasher, faulty turn signal relay. I'd bet the issue is with the turn signal switch itself - due to the fact the problem is only on the left side signal.

if you changed the battery you have to reset the windows and the sun roof, this is done by holding down the control of each glass up and down until you reach the end of its travel and keep well for about 2 to 3 seconds, up or down. With the sun roof also have to do the same, take it to the end of its stroke by pressing and releasing the control, once it reaches the end of its run, maintain control down for 2 or 3 seconds-clockwi, or closing and opening the sun roof

I see this motor for $450 and the part # is 2038203142, maybe you can find it cheaper if you google the number.

Yes, try replacing just the mirror portion of the sideview mirror - rather than the entire assembly (housing and mirror) at much greater expense.
Try the many on-line auto parts sources, such as; www.autopartswarehouse.com, www.partsgeek.com and www.rockauto.com for the replacement parts. For example, they (RockAuto) list the outside mirrors (both left and right) from around $14.00 and around $20.00 each - depending upon which side.

1. Attempt to resynchronize the windows by pressing the window up button until the window is completely closed and then hold the up button for an additional 5 seconds. This will resynchronize the express up feature of the window.

2. Next press the window down button and allow the window to fully open. Hold the window down button for an additional 5 seconds once the window is fully open. This will resynchronize the express open feature of the window.

3. Repeat steps 1 and 2 for each window.

This would be the washer nozzles - these are positioned to aim the windshield washer fluid to clean the windshield along with the wiper action.
