Default Operator problems (formally electrical problems (fixed))

FIXED -- I just finished cleaning my evap, and replacing the resistor pack on my 89 A/T. The AC fan would only run on high setting.

Put everything back together and I have a bunch of electrical problems that I did not have before. The radiator fans want to run non-stop (have to open hood to stop them) no interior lights, the ***** that open the rear lid no longer work, dash analog gauges do not work, dash computer is in-op.

But I do now have 4 different settings for the AC fan

Not a very good trade.

help!

I can cause more work for myself than I fix.
problems were:
1) a fuse I blew by not removing -cable at btty.
2) water on temp sensor on top of motor (doesn't work, but it sure is cleaner).

that would be the temp switch in the rad that could be defective and causing that.

I have not been able to get back to car to verify, but I believe I know the cause.
Prior to HVAC R & R I washed the car, including engine bay.

if the radiator connection for the fans is disconnected the fans will run all the time the key is turned on. Connection point is when facing the engine on the right hand lower corner of the rad on the front.............
