Many owners seem to be having problems with random electrical/alarm issues. Reading through the forums I noticed many of the issues happened after washing and bad weather. My findings.

The crossfire has crappy door locks (manufactured by chrysler I assume) that allow moisture into the system. this moisture sends false signals that involve the door locks, dome light and alarm. The solution.

A spray lubricant that displaces moisture and does not conduct electricity - high quality silicone spray - many types on the market. Just make sure that it contains a high flash solvent that will quickly evaporate and take the moisture with it.

Just spray a bit into the locks - if your car is acting really bad you may need to take the door apart to complete the job.

This works! Check the locking control unit in the truck while your at it.

 

My ford ranger is like that too !!! When door locks get water inside always messes up the dome lights either wont come on or wont shut off til I spray the door locks !!! So I think hes right about our cars too !!!!

 

White Lithium Grease in an aerosol can is usually best for locks, hinges and any moving parts including rear wing....

 

agreed I love the stuff

 

I doubt that the locks were made by Chrysler, Chrysler does not make door locks, they assemble cars made from parts mostly made by others. This car was made in Germany using MB parts mostly so why not use a MB lock.
The lock has a wiring harness on it and it tells the central locking system that the switch has been activated. Could moisture get on it? maybe from water coming down the glass.
Spray in the key hole will not get near the switch. Problems with the alarm have many possible causes and I doubt this is one of them.

 

I would agree with 180 here. Not cheap Chrysler parts. Cheap MBparts.

For the record, our Crossies contain no Chrysler components. None. Zip. Nada. The only thing American incolved with the cars was the contract you signed at the dealer. And likely it was printied on paper made in China.

For real.

Asfor the BENZ part of the equation;
They may claim to be the best engineered cars in the world but are assembled from parts made by the lowest bidder. Had more than a few Benzes over time.

Window regulators, mounting adhesives and locks, not so great. And their alarm systems are just touchy as hell. I owned three SEL's and everyone had the alarm going off for no reason.
(However, despite this, one of them was stolen)

Jeff, you said " Many owners seem to be having problems with random electrical/alarm issues. Reading through the forums I noticed many of the issues happened after washing and bad weather. My findings."

I'm fairly new here but I've not seen anybody complain about electrical problems after washing or storms. It seems most problems are caused from a low battery.
