Default Re: MB air conditioner blockage?

I haven’t checked myself but apparently the fan runs fine when the aircon is switched off but when you turn the air con on something is tripping and telling the car to turn the fan off.
The tech was saying it’s a common issue for the wiring harness to get damaged and cause this problem but If it’s not that then it’s the fans control module which requires the whole fan to be replaced.
Just googling and it seems you can buy a fan control module separately to the fan and it’s not too expensive.
Would it be worth me just replacing that at seeing if that fixes the problem?
I’m so frustrated as it looks like I’ve paid to have the TX valve and compressor replaced for nothing. They obviously won’t admit that but the fact that the same fault exists from prior to them doing this work seems that way. I highly doubt I picked up two seperate issues causing the same problem at the same time.
