Door A-Jar

I have been having a problem with the Door A-Jar light coming on as well as the doom light coming on indicating that a door was open when in fact it was NOT.
I received a very good remedy from one of the forum guys, who's name I can't remember. I deleted his e-mail by mistake. Any way I want to thank him, you know who you are, for his help.
As directed I used the WD 40 to clean the sensor for the door open switch on both back doors of my Ranger. Opened and closed the doors a dozen times or more and the WD40 worked. Because WD40 is a cleaner and NOT a lubricant I then used Fluid Film to Lubricate the latch. PROBLEM SOLVED no more doom Light or Door Open Light coming on. Thanks again for your help.

Very, very common problem.

And your fix was the one we always recommend.

WD-40 does have oil in it, but it's a fairly volatile one. I use only the WD-40 and just reuse it periodically because I don't want grit sticking to the mechanism.

And lol -- it's "dome" light, ha ha! I like the "doom light" concept though!

Yep WD is great but I'm in a cold, snowy, salty Nova Scotia winter so I use the lube stuff for extra protection. No fault with WD though.

CLEANS: WD-40 gets under dirt, grime and grease to clean. It also dissolves adhesives, allowing easy removal of labels, tape, stickers, and excess bonding material.
DISPLACES MOISTURE: Because WD-40 displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits.
PENETRATES: WD-40 loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts.
LUBRICATES: WD-40's lubricating ingredients are widely dispersed and hold firmly to all moving parts.
PROTECTS: WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.



^ everyone is right....WD40 does it all.

Yes, WD40 does have a lubricant in it and over time it drys to a wax like finish. I use it to protect machine tools and parts that are kept inside but may get a rust finish from moisture in the air. I leaves a thin film of wax like finish on my lathe and mill and drill press table and anything else I want to protect. It comes off easily with kerosene.

I don't use it on electrical contacts or switches any more as it has caused some problems. I prefer to use the brake/carb cleaner or the sensor cleaner in a spray can. Then if I want to lube a switch I use silicone lube spray.

WD40 works on door hindges, tailgate pivots,etc..

Don't use it in a lock. There will come a day when you wish you hadn't if you do.

It used to be used to start engines untill they quit using propane for the propelant and now use an inert gas.
