my 1993 Wagon - several questions
hello,
I am from germany and this is my first H1, it is a stock 1993 wagon with 6.2l V8 GM Diesel and the TH400 3-speed gearbox
the car was imported from the us to italy several years ago, I got it without any manual
I hope you could help me with the following questions:
1) does any body have a 1992/1993 service manual, I have one for a 1995 H1, but several things are different
2) fuse plan
3) my wash water pump doesn`t work
4) no hot air from the heater, it blows only cold air out of the ventilation
5) I found two points in the front where no hoses are connected, please check the video @ and @
6) the H1 is equipped with a warn electric winch, the switchbox is missing, is there any other chance to test the winch operation?
7) I found a switch close to the drivers seat, but I don`t know what is the function of it?
many thanks!
Best regards
Christian

Regarding the heater, I located the water shutoff valve close to the airfilter, nothing is moving there.
I will try to replace it as soon as I got a new one. May I will install a tube soon. Currently it is getting pretty cold here in germany.

This water control valve (that sends hot coolant to the heater core) is vacuum operated. If you have a vacuum leak this won't work. See if you have vacuum at the HVAC control unit before going too much further. You either have no vacuum to the control unit, a bad control unit, or a break in the line to the water control valve.
