Chrysler LHS Door Window Switch Guide (1997-2001)
Having trouble with your power windows? Here’s what every 1997-2001 Chrysler LHS owner should know before replacing the master window switch.
- Before replacing the switch, inspect the wires in the rubber boot between the driver's door and the car body for breaks.
- Symptoms can range from a single inoperative window to complete failure of the system.
- Replacement is a simple DIY job that requires removing the door panel and a few screws.
- Aftermarket brands like Dorman and Standard Ignition offer affordable and reliable replacements, as new OEM parts are rare.
Is Your Chrysler LHS Window Switch Failing?
If you're suddenly unable to roll a window up or down, the master switch on the driver's door is a common point of failure. In the 1997-2001 Chrysler LHS, these switches handle a lot of use and can wear out over time. The internal contacts can get dirty or break, leading to intermittent problems or complete failure. One day the 'auto-down' for the driver's window might stop working, and the next, you might lose control of a passenger window entirely.
First, Check the Wires
Before you buy a new switch, take a moment to inspect the wiring. On these Chrysler LH platform cars, the wires that run between the door and the vehicle body can break from repeated opening and closing. Pull back the rubber boot in the door jamb and look for any cracked, frayed, or broken wires. A broken wire can mimic the symptoms of a bad switch and is a common issue.
Symptoms of a Bad Master Window Switch
- One or More Windows Won't Work: You might find that only one window is unresponsive from the master switch, but it still works using its own switch on the passenger door.
- Intermittent Operation: The switch may work sometimes but not others. You might have to press the button multiple times to get a window to move.
- All Windows Stop Working: If none of the power windows operate, the master switch could be the cause, especially if you've already checked the main fuse.
- Window Lock Button is Stuck or Ineffective: The button that prevents passengers from using their window controls may fail.
- No 'Click' Sound: Usually, you can hear a faint click from the switch or a relay when you press a button. A lack of sound can point to a dead switch.
Choosing the Right Aftermarket Switch
For a vehicle like the 1997-2001 LHS, finding a new Original Equipment Manufacturer (OEM) switch from a dealer is unlikely. The good news is that aftermarket parts are widely available and are a practical choice. The two most common brands you'll encounter are Dorman and Standard Motor Products (Standard Ignition).
| Brand | Typical Quality & Notes |
|---|---|
| Dorman | Dorman is known for creating direct replacement parts that are designed to match the original's fit and function. For the LHS, their switches (like part #901-400) are a popular, cost-effective solution. While most users find them easy to install and reliable, some have reported long-term durability issues with Dorman products in general. |
| Standard Ignition (SMP) | Standard Motor Products is often considered a professional-grade aftermarket brand. They state their switches use copper alloy conductors for better electrical performance. They are a solid alternative to Dorman and are a preferred choice for many professional technicians. |
Which Brand Should You Buy?
Both Dorman and Standard Ignition offer a reliable replacement for the original switch. If you're looking for the most budget-friendly option that gets the job done, Dorman is a good choice. If you prefer a part often trusted by repair shops and don't mind potentially spending a few dollars more, consider the switch from Standard Motor Products.
Frequently Asked Questions
Is it difficult to replace the LHS window switch myself?
No, this is a great DIY project for beginners. The replacement is straightforward and requires basic hand tools like a Phillips screwdriver, a flat-blade screwdriver, and possibly a trim removal tool. The entire job can usually be done in under an hour. You will need to remove the door panel to access the three screws holding the switch in place.
Do I need any special tools?
No special tools are required. A set of screwdrivers and a plastic pry tool (to avoid scratching the door panel) are all you should need. Some videos show the switch being held by T20 Torx screws, so having a Torx bit set is a good idea.
My passenger window doesn't work from the master switch, but the passenger's own switch works. Is it the master switch?
Yes, this is a classic symptom of a failing master switch. The internal contact for that specific passenger window has likely failed inside the master switch assembly, even though the other buttons still work.
What is the difference between an OEM and an aftermarket switch?
OEM (Original Equipment Manufacturer) is the part made by Chrysler or its supplier. Aftermarket parts are made by other companies like Dorman or Standard Ignition. For an older vehicle, aftermarket switches are more affordable and accessible. They are designed to fit and function just like the original.
Could a fuse be the problem?
Yes, a blown fuse could cause all windows to stop working at once. Always check the fuse box first before ordering parts. However, if only some windows are failing or the problem is intermittent, the switch is a more likely culprit than the fuse.
