Hey everyone,

I have a 1988 MK3 supra Turbo that has a few issues. after searching the forums to no avail, I was wondering if anybody could help me out. It would be much appriciated.

1. Power Locks do not work(Either of them) were should I start?
2. Fog Lights do not work. If it's not the bulbs, were should I look?
3. Rear Wiper is no longer functioning. Motor Possibly? If not, what should I test/Check?
4. I hear a sound like water rushing after cold starup. Is this something in the coolant system?
5. Ditto the headlight washers. Anywere I should start?

Thank you in advance.

1) Fuses.
2) Fuses.
3) Fuses/Connector/Motor
4) Low Coolant/Burp the radiator/Worst case scenario it's an indicator of a blown headgasket.
5) The headlight washers are relatively simple. There is only a relay and the switch. I'm not even sure if there is a fuse (or really, which fuse they might be on).

Since by TN rules I am not allowed to post a section of them :grumble:, my suggestion would be to find to the Toyota Electronic Wiring Diagrams for the Mk3 Supra (aka TEWD). The diagrams are nice and relatively easy to read.
