Do you have a Mustang. Do you have annoying electrical problems that are driving you crazy?
Although each Mustang is different and can either show just one or many of these symptoms, the list below is the most common, symptoms we know of, but does not describe every symptom. The only way to know if your SJB is bad with 100% Accuracy is to have it tested by a qualified mechanic with the proper equipment.
Common Symptoms of a bad SJB. (this is a broad range of symptoms, your vehicle may only experience one or more symptoms at a time).
- One or More Brake lights is stuck on at all time.
- Battery Drains Quickly When Car Sits for a few days
- Headlights are on bright all the time.
- Turn Signals or parking lights are stuck.
- Power Windows do not work
- Instrument cluster malfunctions
- Dash lights quit working.
The original Smart Junction Box installed in these Mustangs had 2 major problems.
Problem 1: The windshield leak problem. These cars had a bad seal from the factory that allowed rain to drip down on the bottom of the windshield. The water leaks directly into the SJB box, and ruins it.
Problem 2: Poorly engineered part when the car was new. These circuit boards were poorly made, and after a few years of heat and cold, they fail to function any more. There are no repairable parts in a SJB; the whole module must be replaced.
You Must Fix your Windshield Leak before Installing the new box. Our Warranty does not cover water damage.
Many companies and dealers are still selling the old design because it is cheaper and they can make more profit. If you get the old design you will just have the same problem again. We only sell the new design SJB
We are selling a Genuine Ford GEM completely revised module that Will never fail again (as long as you have fixed the windshield leak mentioned earlier). The new SJB is completely redesigned internally by Ford engineers to never fail again
|Important Part Number Information:||The part number on your old SJB will not match the one we send you. We are sending you the newest updated genuine Ford version, with the newest part number. Each time it is revised the part number changes, so the part number you receive from us may be nothing like the original. |
Special Return Policy Applies to this Module
Modules are not returnable for a refund, but are returnable if defective, for a swap of another module during the 10 year warranty period. In other words we will not give you money back for a module, but if it is defective (not water damaged), we will be happy to change it for another module for you.
Why This Policy?
Unfortunately since these modules are commonly bought as test parts to diagnose a problem on a vehicle, we are unable to accept a return of any SJB module for a refund for any reason. Just think about it this way, nobody wants to buy a returned module that somebody else used to test their vehicle, Anything could have happened to it during that time, including shorting it out, getting it wet, breaking connector pins etc. You do not want to buy somebody's problem and we do not want to sell you one.
We want to remain as open and honest with our customers as possible therefore we have instituted this policy. Once you purchase the SJB it cannot be returned even if you have never opened the box, please know that the module is yours to keep once purchased.
The Module does however have a 10 year warranty, and if found to be defective within 10 years, we will swap the module out for a new for you during this time.
