I was doing some cleaning and found my windshield washer bottle, (the rear small one in the engine compartment) to be brittle, my thumb went right through it. So I need a new one, any help?

Also, how do I turn on my headlight washers? It seems that none of my washers work, no windshield, no back window and I can't figure out how to turn on the headlight ones.
Thanks
