I just want to add this becasue, I and everyone else has been there about, paying too much or regretting about car repair.

If your wiper breaks druing the rainy season due, to putting off the situation. You could get in an accident or at the very least. Calling a tow truck to tow your car home for inoperative wiper. How much time, money not, to mention embarassment would that cost you? Confidence that the job was done right and will last long time-priceless. You're still ahead.
