My A/C clutch fuse (#46) keeps blowing when the car is started but a/c is not on. Checked relay, it's ok. Unplugged compressor but the fuse still blows. Fan works, heat works, but no cold air.
View 1 RepliesMy 2005 4.6L 4x4 screw is blowing the 10amp a/c clutch, 4x4 solenoid fuse whenever i turn the a/c on, at times whenever I turn the defrost on. the fuse does not blow when i turn the key to power (no engine start) but when engine is running fuse will trip. I disconnected elect. Connection at compressor and fuse still blows, also seems like no power or life from compressor.

Changed fuel filter and filled up with premium and a can of sea foam. The truck straightened up after that, so I thought. Last Friday it dies in the road, cranks, but no fire.
Has to be the engine, had it towed to the local dealer and they get to look at it Monday afternoon, said the transmission fuse was blown and it keeps blowing new ones, it's in the transmission wiring. I am used to older trucks and was blown away transmission wiring will shut the truck down. I would think the wiring harness to the transmission would be simple enough to check out, can the wiring or solenoids in the tranny cause this?
I own a 2004 F150 Screw Lariat and the fuse # 41 keep blowing. This fuse goes to the cigar lighter and the Diagnostic connector power. As soon as I put the fuse in, it sparks and blows. I have even tried different sizes.
View 2 Replies2008 F350 6.4 diesel. I have the listed truck in the heading, my #9 fuse which is for the interior lighting, lighted running boards and it is a 15a fuse, keeps blowing as soon as I touch the fuse to the fuse box to replace it. I have look at all the map lights and interior lights and can not find any thing out of the ordinary, all of these light were working fine, also my cruise control and the back up sensors stopped working and they are not on the same fuse and the other components that are on the circuit with the crule and back sensors still work, I know that this is a lot of different things but hate chasing electrical ghosts...
View 3 RepliesAs the title states I have a 2001 f250 with the 5.4 4x4 and lately the auto headlight / overdrive fuse keeps blowing. Both seem to function just fine but a couple of days later the fuse will be blown. I am not functioning the OD button when it blows so I'm guessing its something with the headlights. What else does that fuse protect?
View 2 RepliesHere is my problem: A/C not blowing cold air, blower motor working fine, checked all relevant fuses for A/C and R202 relay under the hood. Everything is fine here. Next, low pressure switch, jumped, clutch does not engage. Next removed relay R202 (clutch relay) measured voltages (at female sockets) where pins 1 and 3 would go, voltage OK. Jumped where pins 3 and 5 would go (bypass to see if clutch engages) and it does. Appears that the pressure switches check out OK (low pressure and A/C cycling switch - although this one not sure). CarMD unit was used as well, and no codes generated so perhaps PCM is working OK? I'm stumped, as a loss of GND by PCM or perhaps a corroded or open wire issue??
Also, possible the A/C switch on the HVAC control could be bad, but the light comes on, (doesn't mean switch is good necessarily). The rest of that unit works fine, control ***** that is, fan speed adjusts properly, air flow looks good. It appears this is an electrical problem where the clutch is not getting juice but I don't know the source of the problem. However, I also noticed that when the clutch/compressor was running (temporarily as described above) cold air still didn't come out. This, I assume, would mean I would need to add refrigerant or re-charge the A/C AFTER I get the clutch to engage electrically. 2004 F-150 5.4L ....
My horn fuse on my 2011 LX 570 keeps blowing after first use of horn. What could be causing it?
View 3 RepliesEvery time I step on the brakes, there is a bright spark in fuse #13. My brake lights, turn signals and hazards don't work. At this point my truck isn't drivable.
According to the owner's manual in my truck, says circuit #13 is for "stop lamps, CHMSL/hazard, trailer tow stop lamp, and speed control."
I'm assuming that the hazard part covers the turn signals as well, but I know the cruise control works even when the fuse is blown. I used it last night on the way home (this was before I realized I didn't have brake lights).
So I know I have a short somewhere. The only mods I've done to the lights are the aftermarket headlights, but if the fuse only gets blown when I step on the brakes, I don't see what that would have to do with it. Also, these lights have been installed and working for about a month before this started. The only thing that I did around the same time was install the gauges. I ran the power to them from #5, the customer access circuit.
Are there any other "common" areas for this to happen? I already removed the rear brake lights and it didn't work. I am quickly running out of 20A mini fuses.
Why the 30amp PCM fuse located in the under dash panel would blow. Problem started while truck was running and a simple replace of the fuse would it it back alive again. Now fuse is blowing at ignition on. Truck is 1997 F250 LD.
View 7 RepliesI am having trouble with fuse 23 under the hood blowing while driving. I have read several threads on this issue but still no luck. I have removed all 4 02 sensors and ac relay and still about 1/4 mile down the road the fuse blows, and is giving the shift solenoid A shift solenoid B and the torque converter clutch solenoid electrical circuit. I have checked both plugs on the trans, I even dropped the pan and ohmed the solenoids out. I dont know what else to do?
View 14 RepliesDescription: It will crank over forever but not start. New timing belt water pump, etc, so it is not timing. tried different fuel pump relay. no luck. new fuse no luck. The radio fuse also shorts and blows when I change it. Headlight does not come on, but the cabin "ding ding ding" sound plays. Marker, turning, reverse, and brake lights work.
CHECK ENGINE LIGHT does not come on during key turn. I may know what caused it or it may not. Before all of this happened, my audio system fuse under the hood blow. It blew again after I installed a new fuse (immediately).
One day, the wires on a portable cigarette light pump snapped and the two wires had been touch. I noticed the truck stalled several times when letting off the gas and coming to a rolling stop. The fuel pump relay makes a click noise when I turn the key
My 2007 Focus wagon keep blowing (#30) 10amp fuse. It is connected to the tail lights (when the lights are on), the license plate light, and dashboard lights. I think it is related to moisture as it is worse (keeps blowing the fuse) after a rain. I've checked the taillights and there isn't any moisture there (although when I first found this, both taillight housings were pretty melted). Where to look for the short? Some other discussion groups listed different harnesses, but which one...I have the sinking feeling this is going to be impossible to find (or REALLY expensive)

View 4 RepliesFuse #27 keeps blowing as soon as I shift into reverse.
Prior to shifting, everything works as it should - I've unplugged the rear sensors, back up lights, trailer plug, and each time, fuse #27 keeps blowing.....
Where I should look? Also - looking for a 2003 excursion wiring diagram that shows what all fuse#27 controls?
2000 Model, The fuse keeps blowing on this. I thought it was the cruise control fuse because the cruise kept not working and when I replaced fuse it would work. Only for a little though, then I looked at manual and it says the fuse is for the brake position switch. I am presuming this is just like the old days and that is the brake light switch under the dash. They use to have two wires now there is like five. Anyways I do not see any bare wires or anything that would blow a fuse, is it common for these switches to go out or what??

View 1 RepliesMy dad's 1991 Ford ranger 3.0 2wd just died on him when he was driving home and I checked to see if the truck had a spark and it did not so I replaced the ignition control module, then ignition coil, then distributor and rotor cap(plug) and I put new plugs and wires on it a few months back too. I also checked to make sure that the timing chain was working as well (while I had the distributor cap off). Then I realized that the EEC maxi fuse was blown. I then found a fourm that said it might be the relay so I replaced the EEC and the fuel pump relays while I had them both out. Every time I put a new 30 amp fuse in the EEC slot and turn the key to start it the fuse blows and the truck won't start. What might be wrong?

View 1 RepliesMy truck has been blowing HOT when I put the A/C on. I suspected the blend door actuator and changed it out. I later discovered that the A/C fuse is blowing when compressor tries to kick in. I pulled clutch/compressor plug and fuse still blew. When I pulled plug on pressure switch fuse held. I put a fused jumper onto plug for pressure switch and fuse in cab held but fuse in jumper blew. Put cheapo can gauge on low side and it went to "warning' status (high, without compressor running). Is it a clogged something or is it electrical?
