SOURCE: Keep blowing EFI fuse in

Hi, there are a lot of components running on that fuse. What I would do is disconnect things, put in a fresh fuse, and then plug things back in one at a time with the key on. Check the fuse after plugging in each component to see if it burns. Then you will know which part is bad. A good start would be to pull out the circuit opening relay and disconnect the oxygen sensors as well as the EGR valve and air flow meter. Put in a fresh fuse and plug these back in one at a time checking the fuse each time. If the circuit opening relay causes the fuse to burn, the problem is probably the fuel pump.

My window wipers work but my window washer fluid doesn't work is there a fuse for it and if so were is it cause I can't find. Also under the hood fuse box has CMH on it but when I opened it up there was...


It sounds like the seal in the washer pump has worn and let washer fluid into the little motor, causing it to corrode and seize. Pump is usually located on bottom of washer fluid bottle.

How to remove a broken battery fuse 100 amp from 1991 toyota corolla


On the sides of the fuse box, two bolts are holding the fuse down in place. I believe you need a 10mm socket to remove the bolts. Then, the fuse should slide right out.
