SOURCE: Blowing Fuse

There are a few possibilities here. First, you may have high starting amps on the compressor. You mentioned the run capacitor being changed. I'm not sure if you have a start capacitor, but that should also be checked. If you don't have a start capacitor, I would recommend having a hard start kit installed in the unit. It's basically a start capacitor with an internal relay to take it out of the circuit when the compressor is running, and wires up in parallel to the run capacitor. Also, check all of your line voltage wiring. Make sure all the wiring connections are tight (wire nuts, screw terminals, etc.), and that there's no issue with wiring insulation rubbing off from vibration, etc. Finally, check the points on the compressor contactor. If the contacts are black and pitting, it causes arcing, which means excessive amp draw through the contactor.

SOURCE: towing with automatic in overdrive

YES! The owners manual states explicitly that "O/D Off" should be engaged whenever you are towing, I always ignored it for towing under 3000 lbs. The only way I would try it with our 4R100's is with a 4-5 plate Torque Converter Clutch and a Wood/IPT/BCS/Banks rebuilt unit running a separate cooler. The problem originated when Ford shifted to a Pulse Width Modulated (not just on/off) Torque Converter Clutch solenoid for "smoother" shifting. The increased slip in these clutches resulted in faster wear and higher heat levels... and blown solenoid packs. Another $150 down.
PS. You will not see any change in the tranny temp gage in the dash until the temp is well over 230F... too hot for Mercon! Get an aftermarket gage pod to keep an eye on things.

More likely that the solenoid in the transmission is shorted to ground. Has any new electronic equipment been installed recently, like stereo, alarm, etc?

SOURCE: Overdrive switch blowing fuse on 2002 F150 Ford

Remove the shroud around the steering column and shifter and look closly at the wires coming out of the shifter at the pivot of the shifter, if its not to bad you can tapeit and reposition it and be good to go.

Why does the fuse immediately blow on my power door locks? how to fix this?


You have a short somewhere in the system. Maybe one of the lock actuators or a switch. To test disconnect all locks and switch then replace fuse if don't blow start with driver door and reconnect lock check fuse see if it blew if not reconnect switch active lock check fuse see if ok. Continue with each door separate using same steps until fuse no good you will have found short. Replace shorted part.

Replace the transmission range switch for starters, if that doesn't correct the problem you have have a shorted shift solenoid on the valve body inside the transmission.

I have seen multiple trucks with similar fuse blowing problem and have found most are caused by a shorted out overdrive switch or wiring inside the steering column. Usually this is triggered by moving the shifter or something on the column though usually the shifter since thats where the overdrive switch is mounted. If the wiring is the problem after the connector in the column then you have to replace the entire shift lever since the wiring for the overdrive switch is integral to the shift lever.

Cannot disengage overdrive on 2003 Ford F150 4.2L


Check the Fuse for the OD function, this is cab fuse panel fuse #29, 5A.
If This fuse is blown, chances are the wires at the end of the shift lever are chaffed and causing the problem. This happens some times ( can't say why ), but it is simple enough to check and repair the wires if the insulation is chaffed.

The light on my overdrive button doesn't come on, but it also doesn't take my engine out of overdrive. Is this still a fuse related issue?


The OD off switch is powered by the cab fuse panel, Fuse #29 ( 5A ).
If this fuse is blown, could be chaffed wires at the base of the gear shift lever, where they turn out of the chrome tube( behind the plastic cover ).
Without this fuse working, the PCM cannot be signaled to take the truck out of OD, so it could just be the fuse causing the issue. Please add a comment on what you find on the fuse.

Is there a problem with my engine


E = error. Have dealer run scan test for fault codes.

Electronic Transmission Error Indicator
The vehicle is equipped with a redundant electronic gearshift indicator. This character appears with the key in the RUN position and displays the same gear selection as shown on the selector lever floor console next to the range selector lever. If an "E" character flashes or remains on this indicates that a transmission malfunction has occurred.

Overdrive button on extend cab ford f150


Problem Solved Look No Longer. Overdrive switch fuse blown, auto door locks not working, fuse after fuse after fuse, chasing wires grrrr. Remove the steering column cover (3 screws from the bottom) opens like a **** shell. Your switch is located on the shift lever, the wire for the switch is routed through the handle and comes out where the shift lever mounts to the column. Look very closely at the wire in this area. Most likely rubbed through. MR
