Fix 2022 Grand Design RV Window Shades with Replacement Springs

Repair or adjustment may be possible, but the question does not identify the shade system or establish that a spring has failed. A 2022 Grand Design coach designation does not determine the shade maker, roller diameter or revision. The earlier answer supplied a ¾-inch tube measurement that was not in the question; do not use that assumption to order a part.

Identify each affected shade by its maker and product line, label or revision, shade width, actual metal roller-tube outside diameter and both end fittings. For a day/night assembly, identify the two rollers separately. A shade that retracts but will not remain lowered presents a stopping or operation question; that symptom alone does not establish a failed spring or a universal adjustment.

Irvine's replacement-parts reference distinguishes ¾-inch and one-inch Valu-Line springs, Slow-Rise springs and separate auto-stop components. The ¾-inch Valu-Line spring listing is a reference for an applicable Irvine mechanism, not a confirmed replacement for this Grand Design RV. Match the original assembly and manufacturer size guide; tube diameter alone does not settle spring length, end fitting or stop compatibility.

For a positively identified Irvine Slow-Rise shade with the illustrated controls, the manufacturer's operation sheet distinguishes upper-stop and retraction-speed adjustments. Do not apply those controls to a different Valu-Line or unidentified mechanism. The earlier end-cap removal and “slip in a spring” procedure was not supported for this shade. Use the identified system's service instructions or qualified shade-service help rather than opening or winding an unknown tensioned assembly. The exact fault, replacement and repair outcome remain unconfirmed.
