#17 fuse?

[burnteggroll]

can someone tell me what fuse is #17 in a '94 sho? my #17 keeps on shorting out, trying to find the culprit. my car didn't come with a owners manual. while i'm at it, what's the best sho specicfic manual to purchase. thanks for any info.

burnteggroll, (I like that!)

The best Shop Manual for ANY Ford product is the Ford Service Manual published by Helm. You want the Taurus/Sable manual, which will include the SHO (Taurus).

In my 90 Shop Manual it lists the #17 fuse (15 amp) as being for the A/C compressor clutch coil and the EATC blend door actuator. I do not know if it is the same for your model year.

You can disconnect the A/C clutch coil at the low pressure switch on top of the accumulator/dryer, or at the clutch coil itself. The blend door acuator is buried under the dash. Does the fuse blow when you have the defrost on?

There should be a diagram of the fuses on the back of the fuse panel cover plate.

You may still be able to get the Helm manual (new) from Helm for your 94. You want the Workshop Manual and the Wiring Diagrams. You may also be able to get an owners manual for your model year if they have any left. shrug

burnteggroll,

I forgot, you may also want the "Electrical & Vacuum Trouble-Shooting Manual" for your model year, if it is still a separate item. rangerj

For the 94, F17 (15A) supplies: EATC BDA, A/C Compressor Cluch, A/C Heater Control Switch, and the Blower Motor Speed Control Module.

Your best bet is to locate a service CD on eBay. Originals will cost around $20-25, bootleg copies can be purchased for less than $10. There is a member here who has a supply of originals (not bootlegs) who offers them for sale, but I don't recall what his handle is.

thanks to both of y'all. here's the deal. i left an earlier post about smelling something burning, then when i run heater a few days later, no heat. when i checked the fuses, i see #17 blown. i put 2 back in, then they blow. so i'm figuring something fried in one of those things that runs off of #17, thus causing the short. are those things hard to locate? thanks for the info. and i'm planning on getting the cd and manual, if both will help. oh yeah, what's a blend door actuator?

 

[burnteggroll]

one more thing, the fan still blows, and everything is normal other than no heat being generated.

burnteggroll,

I will assume that since you have a SHO that you also have the automatic climate control system.

So, If the blower motor is functioning, that is it works at all 4 speeds, and you are not getting any heat with the control in the "HEAT" position, then the blend door motor is suspect.

The blend door motor is ontop of the evaporator core, which is behind the glove box. This does not mean that the blend door motor is bad, but it should operate the blend door until the fuse blows.

The other possibilities are the blower motor and the control unit. The blower motor could be working. but drawing to many amps and blowing the fuse. There are test to determine if this is the case.

You can find the test of the control unit, blower motor, etc in a service manual at the library, or waite until you get a service manual.

I tend to want the physical books, but as Steve has pointed out, the CD is much less expensive and does not take up as much space.

You either have a shorted wire, or an electric motor that is binding and drawing too much juice (amps), or shorted out (usually in the windings).

The switch in the control unit is also a possibility, but less likely.

You need the drawings and schematics provided by the service manual to pinpoint your problem. I wish I could tell you in 25 words or less how to solve this one, but its going to take some time and effort to get at the components, and the reference material to tell you how to test them. rangerj

rangerj, i really appreciate your time on that reply. i'm going to look into it shortly. down here heat isn't needed as bad as up there, so i can at least take my time. thanks again.

Fuse 17 is the EATC blend door actuator, A/C compressor clutch, A/C heater control switch, and Blower motor speed controller.
