I acquired some new hoses, connections, nozzles, ect lately for my original pneumatic powered windshield wash
system. I could never get the system to work strong after the PO caked the spray nozzles with multiple waxing, and leaky hose between the tire and the wash tank. It would only spray out of two of the four nozzles for a few hours, before the tire lost pressure, but still worked. Yesterday I put a fresh hose between the tire and tank, and replaced the spray nozzles. Now I have a new problem. Once the tank is pressurized to 42psi the system will spray for about 1/2 second then it stops working. The tank is still pressurized, and I detached the hoses from the spray nozzles, still no spray. Every time I drain the pressure from the tank, and re-pressurize I get one interval of 1/2 second spray, then nothing. I took the tire hose and hooked the system up backwards. I successfully blew bubbles in the wash tank when pulling on the wash wand with this attempt. I thought this would clear the system with a backflush. I them hooked the system back up normal, except for the spray nozzle hoses jest hanging free to eliminate the new nozzles from the test I still get the same 1/2 second of wash, requiring a pressure drain reset for another 1/2 second. Is this indicating a bad steering column control. I’m considering rigging up an electric pump system, but am willing to try a few more things to get the original, quirky system working again. |
