2003 Mercury Mountaineer Electrical Problems?!?!?!

O/D Light Blinking Like its Not in Overdrive, But it goes into Overdrive fine. After driving for a minute or two my radio turns off, DVD player will Not turn off and keeps trying to read disc. I believe the "accumulator" continues to run in the rear a/c, makes a clicking noise even though it's turned off. Car Runs beautifully as far as transmission and engine wise. Could it be PCM? HELP!!!!!!! -Donna

O/D light flashing is telling there is a problem with the transmission an trouble codes are stored . The clicking you hear in the rear climate control system is mode door or blend door actuator . There is no accumulator in the rear A/C system . If the A/C system had a accumulator it would be in the engine compartment . Your best bet ,take it to a qualified repair shop.

SOURCE: 2001 Mercury Mountaineer won't start

Have a load test done on the battery. If it checks out good, take a voltmeter to the battery and have an assistant rotate the engine. If you see more than a 2 volt drop when the car is being started, the starter is heading south.

SOURCE: 2001 Mercury Mountaineer keeps blowing the PCM power diode (fuse #19)

Check all of the battery terminals and cables and check the wires on the starter/selonoid, start from the battery and follow the cable out and check all conections , clean and tighten them and if it still does it the starter/selonoid is bad and needs replacement...

SOURCE: 2003 Mountaineer won't start, battery is good.

CHECK BATTERY CABLES AND FOR CORROSION,A BAD GROUND OR BAD CONNECTION WILL CREATE ENOUGH RESISTANCE TO PREVENT STARTER TO CRANK OVER ENGINE. IF BATTERY HAS 12V DOESN'T MEAN IT'S GOOD,IT COULD HAVE ON 100 CCA'S, NOT ENOUGH.

My husband had the same problem with his 02 Mountaineer about 6 months ago. I read somewhere that if you take WD40 & spray the door locks it should stop. We tried it & so far it's worked. Good luck!

SOURCE: Heat does not work, makes loud clicking noise when

I have a 2003 Mountaineer that had the same symptoms. After doing some research, me and Google decided it was the Blend Door Actuator. It is a fairly difficult job due to having to take pretty much the whole dash off, but I did it myself with minimal experience. I included a few links.

Over heat light goes on 2003 mercury mountaineer loses engine power engine isn't over heating

It could be a bad temperature sensor producing a false warning. Also, check the oil....sometimes low oil levels could cause the overheat light to come on. Next, have it check out by a mechanic

1997 Mercury Mountaineer Overdrive flashing

When the OD light flashes it means the transmission has developed a fault. As to what the fault may be is yet to be seen without the system being scanned. In many cases the light indicates the transmission is slipping, you may not feel it slipping, but the computer (called the PCM) senses it through the internal speed sensors that measure main shaft input speed and shaft output speed in RPM. Other problems like shift solenoids can cause this as well. Another factor can be the transmission fluid is worn out, it should be replaced along with a new filter every 60,000 miles minimum.
