ALTBET Window Lift Switch 2-Pack 5-Pin Driver Side for Peterbilt 365-389 — Direct-Fit Durable Replacement

If your Peterbilt’s driver-side power window switch has failed, this pair of ALTBET replacement switches offers an affordable, robust solution engineered to match OE fit and function. Each switch is built for heavy-duty cab environments, intended to reinstate reliable up/down control while resisting everyday wear. The set replaces part numbers 1609209, 1609209PKG, and 577.75607 and ships as two driver-side switches so you have a spare or a matched pair for dual-vehicle maintenance.

How will this switch improve my truck's window performance?

Installing these ALTBET switches should return consistent electrical contact and smooth window motion compared with a worn or intermittent original. They are manufactured to withstand frequent use and cab vibration typical of long-haul operation.

• Direct-fit design mimics original mounting points and connector layout for a snug replacement.
• 5-pin electrical interface restores full driver-side control for both up and down functions.
• Durable materials resist routine wear for extended service life.

Will this part fit my Peterbilt model and how do I confirm compatibility?

These switches are listed for Peterbilt 365, 367, 384, 386, 387 and 389 models—matching the common switch assemblies used on those cabs. Before ordering, compare your existing switch’s part numbers and connector shape to ensure a match.

• Replaces part numbers: 1609209, 1609209PKG, 577.75607.

How difficult is installation and should I seek professional help?
