Why won't my Crossfire's rear spoiler go up or come down?

Short answer: The Crossfire's power rear spoiler rises at about 60 mph and drops at lower speed. When it stops partway or won't retract, owners most often trace it to a limit switch (a small switch that tells the computer the spoiler is fully up or down) or binding in the mechanism, not the motor. Check for binding first, then the switches and wiring.

Symptom: The spoiler warning light; the spoiler lifts only partway; it goes up at highway speed but stays up until you shut the car off; the manual spoiler button doesn't work.

What to check first

1. Press the spoiler button with the car on to see whether it moves manually.
2. Look for binding: dirt, a bent arm or something blocking it.
3. Check the limit switches and wiring under the spoiler. A switch that's stuck or grounding early can confuse the body computer.
4. Check the battery and grounds. Low voltage can cause odd electrical behavior.
5. Read body codes with a scanner that can talk to the body computer (BCM).

Likely causes

1. Faulty spoiler limit switch. Owners traced erratic spoilers to a lower or upper limit switch.
2. Mechanical binding in the spoiler arms. Check this first.
3. Wiring, ground or body computer problem. One owner replaced the BCM before finding the switch.

What it usually costs

Owners in these threads didn't post shop prices. A limit switch is an inexpensive part; replacing the body computer costs far more, so rule out the switch first.

Is it safe to keep driving?

Yes. The spoiler adds stability at high speed, so if it stays down, keep highway speeds moderate until it's fixed. Verify with a mechanic if you're unsure.

DIY or shop?

DIY for most owners. Owners replaced the limit switch themselves. The body computer is a shop or dealer job.

Recalls, bulletins and complaints in plain words

• Service bulletin: An owner in the first thread mentions a Chrysler service bulletin for the spoiler; ask a dealer to check your VIN.
• Recalls: NHTSA lists no recall for the rear spoiler on the Chrysler Crossfire in the model years we could check on 2026-10-23 (the recall lookup returned an error for 3 model-year queries). Check your VIN at nhtsa.gov/recalls. If your car is part of a recall, the dealer fixes it for free.
• NHTSA complaints: 29 keyword-matched complaints for Chrysler Crossfire 2004–2008 (of 708 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-23; keywords: spoiler). This counts complaints that mention these words. It is not a defect finding.

What owners report

• In Spoiler not deploying completely on CrossfireForum.org, a 2005 Limited convertible owner's spoiler wouldn't lift fully. The site admin said to check for mechanical binding first, then the upper limit switch, which can ground and signal the body computer too early.
• In Erratic Spoiler Fix — Limit Switch Source Identified, a 2007 Roadster owner at 17,000 miles had a spoiler that went up at about 62 mph and wouldn't retract until he cycled the ignition. After replacing the body computer, battery and grounds didn't fix it, the thread traced the problem to a faulty limit switch that was replaced.

Quick tip

Don't let anyone sell you a body computer before checking the spoiler's limit switches.

Vehicle focus: 2004–2008 Chrysler Crossfire coupe and roadster with the power rear spoiler (SRT-6 models have a fixed wing).

Safety / mechanic note

The spoiler adds stability at high speed. Verify with a mechanic.
