Wiper problems of the 2005 Volkswagen Beetle

My VIN number on car is different from the VIN number on motor. I just found this out about one month ago. I wasn't told this when I bought the vehicle. . So, I don't know if this is a big problem or not. Its a 2005 vw, with a 2004 engine from a slavage yard, bandb, or b and r?? this caused me great alarm. The wiring since had to be done about 2 weeks ago. Also, the belly pan had been missing. I had it fixed. And the headlights had to be repaired too. This car has cost me thousands in repairs since purchase. And I don't have more thousands to put in it. Please help I hope the car in excellent shape now. Also, I noticed the dip stick broke to oil check and hadn't been prior to my acknowledgement. Also, the car has a soft top and I was told was newly replaced in 5/2018. But it seems to have a different look inside then a tight shape regarding top, and I don't know if this should be or not.

Rear window regulators went out.

The problem is with all vw Beetles in this time frame. The hvac doors have a foam around them that breaks down and falling into the duct work of the vehicle. When you are driving the vehicle with defrost or ac on these little pieces fly out of ducts into your eyes. If you have glasses it is a little better till the pieces hit you because you turned your head. I have pictures if needed. Of course vw states there is know product they heard about.
