After noticing my windshield washer pump was not working (I checked the line and it's not clogged) on my '88 Cressida, I decided to replace it. After doing that, it still didn't work, so I'm thinking the fuse for it must be blown. The electronic connections seem to be working. When I first worked on this, I had a friend pull the stalk for the "mist" setting to test the old pump before I replaced it. He just told me there was a small puff of smoke after he pulled it! He said it didn't smell like fried electronics, but I don't know why he didn't tell me earlier. Either way, I replaced the pump with a new one.

Because of this information he just told me, I went out to test the wipers and the actual wiper settings work. But now, when I pull the stalk for "mist," nothing happens at all. I'm absolutely confused with this situation. Do you think some sort of electronics shorted out or a fuse is blown after all? Right now I have some replacement fuses for the wipers, but a.) I'm not sure where they go and b.) I'm not sure if I need them if the wipers work when I'm not using "mist." Hopefully that makes sense.

To see if there's something wrong on the steering column controls, is there a safe way to remove the steering column cover without cracking it (I haven't done this before)? Second, if my problem is at the switch, does anyone know where that is located and how I would replace it?

Unfortunately, I don't have a repair manual and I could only find $60+ repair manuals on eBay. Does anyone have one they'd be willing to sell for a better price? Or, better yet, know of one that I can use/download online? I feel like I'm really close to figuring this one out, but I'm not sure how to safely remove the steering wheel cover so I can see what's wrong with my wiper spray switch.

Worst case scenario, would a Toyota (or independent) mechanic be able to fix this for me without it costing a lot of money? Thanks in advance, everyone, I appreciate your help!
