a/c turning on and off
my ac was blowing at very low speed, couldn't even feel it. Took to MB dealership they diagnosed it to be the voltage regulator.. told me it would cost $1600 to replace... 600 for the part and 1000 labor. I decided to replace it myself. Got the new one installed in about 30 min, but now it blows good but then starts cutting off and on by itself and after about 7 or 8 times cutting on and off it stays on but blows really low again?? Any ideas 💡 should I replace the blower motor? Any help is greatly appreciated 🙏 🙂 ☺
Ps... forgot to mention that if I manually turn the ac off and on before it starts its cycle of on/off... it will blow at high speed as long as I keep turning on and off quickly

I would try the blower motor next and if not that perhaps the regulator it is attached to.
Always helps if you have an advanced scan tool, like iCarSoft, to diagnose and pull codes.

Update blower motor going on and off by itself
Went out and got a blower motor.... it didn't fix my problem still cutting off and on by itself until it eventually stays on but blows little to no air.
