i have two windshield washer fluid pumps both for the front windshild. the resistance for the one that came with the car is 7.3 ohms and the other one i baught offline is 2.5ohms. they both sounds like they work but i am getting no pressure to spray the fluid out of the jet sprayers. i live in pa could the lines freeze? the washer has de-icer in it and its not frozen in th,e resivueor. not sure what the heck is going on here. any ideas?
