Chrysler Repair: engin cooling fan, compressor clutch, document scanner

Question
I have a 93 Caravan SE, the van only has 66000 miles on it. It is getting old and starting to fall apart cosmeticly but,still starts every time.I had to change the braket between the trans housing,the engin and, the front motor mount.When it broke, the motor droped foward and the dipstick ran into the cooling fan and stoped it. Now that I fixed that, the fan dosen't come on and the motor overheats. I've been trying to troubleshoot the problem by the proccess of elimanation. But I can't find the location of the power distibution center, I know it's usualy under the hood but the only fusebox I can find is in the dashboard in the car. I figure to start tracing from there. All the newer models have an additional fusebox on the side of the battery but, I just can't find it in my model.   Thank You, BOB

Answer
Hi Bob,
Thanks for the positive feedback. I need to xerox copy and mail you the pages because I don't have a document scanner. So let me know a postal mailing address. Also, mention if you have a manual or an automatic trans as the wiring is different for the two.

Hi Bob,
The power distribution center didn't appear in the van until sometime after '93. Instead the high current main power circuits were handled by fusible links, which are solid one color wires (look like colored spaghetti) of various current handling capacities and which act like fuses. When they blow you have to cut out the damaged section and splice in a new one. The main current supply to the fan motor and the A/C compressor clutch comes from an orange color fusible link that itself is spliced to a gray wire that feeds both the low and the high speed fan relays mounted on the left fender shield and also the A/C clutch relay which is mounted on the right fender shield (there are a number of relays mounted around the outside paneling of the engine compartment). The best way to find the fusible link is to trace along the fat black wire from the + post of the battery to a point behind the battery where it is spliced together with 7 solid color wires which are all fusible links of several colors but there is only one orange link and if that were blown that would kill the radiator fan and the A/C clutch function. You can usually tell if the link is blown by pulling on both ends and see if it feels solid or mushy and in fact tears apart. There is a separate supply line for the activating coils of the relays and that is a dark blue wire that comes from the ignition switch which itself is supplied by a red fusible link that has its inception at the same major 7 fusible link splice. So check also that red fusible link. You can check whether there is power getting to the high and the low speed fan relays (which are the most forward and the most rearward of the 5 relays mounted on the left fender shield) by checking the gray wire at the relay sockets (should be hot all the time) and the dark blue wire at the relay sockets (which should be hot when the ignition switch is in the run position). So I would examine those 2 fusible links and the 2 relay sockets to find out if you are getting power to the relays that run the 2-speed radiator fan motor. If so, then the fan may be bad (you could try jumping directly to it from the battery, but tell me which engine you have so I make sure to give you the correct wire colors to jump at the fan; there is a different wiring diagram for each of the 3 possible engines).
So that will get you started. I can xerox and snail mail you the wiring diagrams for your van because I have the '93 Chrysler shop manual.
