Just bought a 1987 Iroc Z. Need to know why my

Sometimes disconnecting the battery does more damage then you want it might have trip a fuse or relay check those if thats not it, maybe wiper motor or transmission went out.

Sounds like you may need to change the washer fluid pump. They do go bad. It's located inside the washer fluid reservoir, which is in the front of the passenger's side wheel well, behind the front bumper.

This reply falls under, " what else should I look at."

When you press to squirt, do you hear any sound? if you do there are 3 easy things you can do.

1. Some of the windshield wiper reserviors, ( plastic bottles ), need a minimumlevel of fluid to operate, so, make sure you fill up your reservior.

If that doesn't help;
2. There is a very small hose that runs from the reservior to the pump, pull it off of the pump end, very carefully, and have someone hit the squirter.

If fluid comes through the hose;
3. Take a very small paper clip, straighten one end out, and push it into the ports that the water shoots out of to squirt the windshield.
Sometimes wax or debree can clogg these very little holes.

You are on the problem from what I read. The fluid goes from the tank, through the motor you hear, and out through small tubing to the "nozzles" that spray your windshield. I'm sure one end fell off, but you will have to search it down. Follow the hose if you can, as you may have to move some covers or parts, but look close and you may see the problem.

go to a service station with an air compressor and with the air turned down to about 20 lbs blow into the washer top small hole to force fluid thru the hoses,not a lot of pressure so you blow hoses off or rupture something

it's likely the tiny motor/pump located at the bottom of the tank that has failed. to confirm this have some turn on the washer fluid switch and test for voltage at the pump. there are several aftermarket pumps you can use as a replacement.

Check for power at motor connector when switch on. If power there, it's probably the motor. Check fuses first.

Either the pump is bad, or the nozzles are clogged.

Hello, Spray some wd-40 etc at the joint that the wiper blade pivots on and then work it back and forth. Sometimes you really have to push harder than you thought it could stand.
I hope this helps.

On my 850 the headlight wipers come on the same time as my windshield wipers when I pull the lever to squirt washer fluid on my windshield.
The back wiper should be on an independent switch.
