Question about 2010 Jeep Wrangler

2 Answers

Why do the headlights work all winter when it's cold and dry, but as soon as it warms up and gets damp, they stop?

We have already changed the multifunction switch last year when this was happening and now doing it again as the weather changed

There are grounds for the ehadlights. I don't know exactly where they are, but one of the wires from the headlight connector shold got straight to the body or frame. A bad ground can cause such problems. There shold also be a headlight relay. You might want to change that as well, or at least get a can of spray electric contact cleaner from the auto parts store, pull the relay, spray the contacts on it and spray into the socket. Check the headlight fuse also -- change and spray contact cleaner in the socket.

2006 ford free star when it rains the PCM gets wet and runs rough. Today it has rained for 3 days @ won't turn over. Battery is fine. Only a problem when it rains.


Rain should not affect your car starting. It sounds as if your battery is failing. Put your headlights on and get someone to turn the key with you looking at the headlights. If they dim to a glow-worm, your battery is not powerful enough. Sometimes a cell will fail and although your get 12 volts, you don't get enough cranking amps.

Regarding starting in damp weather, you can try this. Spray all the ignition leads with WD40 and also the inside and outside of the distributor cap. You can also try this which worked for me on an old Datsun that didn't like damp weather. Get some broadsheet newspapers and tape them together to make one large cover for the engine compartment. Make is about 10 sheets thick. Run the vehicle with this all over the winter. When you drive the paper warms and keeps the leads warm. When you park, any moisture in the air goes into the paper and doesn't condense on the ignition system. Make sure the paper is away from moving part like the radiator fan and the exhaust manifold. Check it after your first short drive, it should stay in place.

Raining for 3 days and my 2006 ford free star won't turn over. Battery is good, starter clicks no more. PCM has been wet before. Waiting for dryer weather and try again.

2002 madza protege 4 cyl had new ignition coils, wires, plugs and egr valve, fuel system clean out but still wont start after cold damp night and sitting 8-16 hours. After day warms up to 50-60 it starts...


Symptoms are indicative of a partially broken wire somewhere, the cold increases the resistance in the wires and if they aren't working at 100% to start with, will cause your problem. I think you are on the right track, I would replace any high tension parts not already new then start looking for wires showing a high resistance. Check and clean ( with contact cleaner aerosol ) any and all electrical plugs in your ignition system. I would try drying out your computer and packing around it with silica gel to keep it dry.
Good luck
