It should. It's a 10 amp fuse in the box down by the clutch pedal titled "rear wiper". Even if you dont have a rear wiper, this fuse is needed for the climate control circuit. Most people with this problem seem to have been able to just replace the fuse and all is good, but it just keeps blowing on mine. Hopefully yours is a one-and-done fix.

 

Bump. Are there any electrical gurus here? Circuits are not my strong point. What would cause the rear wiper fuse to keep blowing?

 

You have a short somewhere. It could be a pinched wire, a wire that has chafed insulation that is grounding on bare metal or some component that has an internal fault that is grounding the circuit. Really the only thing to do is review the schematic for this circuit and determine everything that is powered by it, and start troubleshooting - for example, you could unplug each component that is powered by this circuit and see if the fuse still blows. If it doesn't, then that is pointing towards a component problem (or a wire that was grounding that is no longer grounding due to being displaced by the unplugging. Plug in each component one by one (with the ignition off each time), and see at what point the fuse breaks. That can narrow down the fault and you can then inspect/replace/swap the potentially bad component.

If the fuse blows with all the components unplugged, then that is pointing towards a wire short somewhere. You will have to get out a volt/ohm meter now and check each current-carrying wire for resistance to ground, figure out the offending wire, trace it back to where ever it is grounding, and repair it. This is a tedious process.

Considering the nature of some owners of FD's (or shops) to hack into the wire harness for whatever reason along with related abysmally poor wiring skill , I suspect that the problem is likely human-caused rather than a completely vehicle-only problem.

 

jza80, thanks! It wasnt what i was hoping to hear, but kind of what i was afraid of. Was really hoping for a "oh just replace component x that usually causes this" type of answer lol.

 

Hi Buddy! I Know this was decades ago but I have this same problem and its not the rear wiper fuse etc. when you say "re soldering the circuits attached to the controls." what circuits did you do exactly?

I'm on Lockdown due to COVID 19 so I'm trying to finally sort this Climate Control out once and for all ha.

Any advice would be great,

Cheers.

 

Can’t open the blower resistor link where is it located please
