01 TAT 225 questions

This is my 01 TT 225, bought for $5,500 at around 96-98,000 miles. Overheated thebdaybi got it and spent over $4,500 to get then issues fixed amd it drives good now. But the clutch is worn out bad amd it's quoted at around $3,500-4,200, plus my oil sensor came on and something happened to the climate control at the same time. it just shorted out and changing fuses on the drivers side doesmt work. But I have lights, it starts, gets great gas mileage and is fun to drive but what could have happened electronically? I'm wanting to her thr clutch fixed ASAP too so I dont damage anything else. 3rd owner problems🙄
