i remeber a few years back i thought my heater core was toast because the fan only blew high and not low.  I was all set to blow tons of $$$ on a heater core till i decided to ask a dumb question on Zukiworld.  turns out the question was not so dumb, i saved 1000's to only to find out it was a $15 part in the blower fan.  Glad i asked that dumb question.  so i'm going to ask another and hope I'm wrong.....

My windshiled washer pump is not pumping anymore.  The wipers work and the fuse in the box is fine.  Is the motor/pump dead or is there some inline fuse i should check first?

check for blocks or leaks in the tubes

i had to replace mine once

X2 on the clog, but easy enough to check the pump. Key on & go over by the washer reservior, have someone pull the washer lever & listen... noise (whrrrrrrrr)? no noise? Could be wires/connector to the pump... bust out Voltmeter... hot/ground... power? If you have power but no 'whrrrr' pump is dead... just like any other, they don't last forever... good news is they're cheap & really easy to replace. Just mounts to the bottom inside of the resvervior. Two bolts on mine hold resvervior in, looks like the pump just clips to the side. I'd have to take it off to see how it seals. If it's less than 1/2 full you prolly could just tip the tank on its side & swap out the pump w/out even emptying it. hth
