UCH fault?

[Mark5290]

My brother carried out an oil and filters change on his mates 172, not sure what age the car is though, and i think he said it was an import aswell, but his mate said that his passenger window does not go up/down off any of the window buttons and when he switches his interior light on it does not illuminate, instead it brings on the airbag warning light on the dash:S, i am wondering whether this could be a UCH fault or is it something else.

Sounds like it to me.

I had to have a new UCH unit because my drivers window kept winding itself down randomly.

Sounds very much like it. Check fuses for the interior light but i'd say the UCH has taken a s**t tbh. Thats going to be expensive.
