This is one of the few jobs on a T1 Silverado that needs almost no tools. Both front blades are 22 in and use the common hook (J-hook) arm end, so aftermarket beam or conventional blades fit directly with no adapter. The 2.7L turbo, 5.3L L84, 6.2L L87 and 3.0L Duramax trucks are all identical here, and no Silverado 1500 has a rear wiper.
The one thing people get wrong is trying to yank the blade straight off the hook. There is a small plastic tab on the underside of the connector that has to be pressed in first, and the blade then slides down along the hook. Force it and you bend the arm hook, which leaves the blade riding unevenly and streaking. The other common mistake is letting the bare metal arm snap down onto the windshield - lay a towel on the glass before you pull the old blade off.

| Microfiber towels 2-3 clean towels Wipe the glass and cowl clean before fitting new blades. | Consumables | shop |
| Glass cleaner Ammonia-free automotive glass cleaner Removes road film so the new rubber does not chatter. | Consumables | shop |
| Small flat-blade screwdriver 3-4 mm blade Depresses the plastic release tab on the hook-style blade connector. | Required | shop |
| Needle-nose pliers 6 in Helps squeeze a stiff or corroded release tab and pull the blade off the hook. | Recommended | shop |
| Nitrile gloves Keeps grease off the new rubber and your hands out of the cowl edge. | Safety | shop |
| Front wiper blades 22 in driver and 22 in passenger, hook/J-hook mount The replacement blades; both sides are the same length on the T1 Silverado 1500. | Parts | shop |
| Isopropyl alcohol wipes 70% or higher Final wipe of the new blade edge and the glass path to cut silicone/wax residue. | Consumables | shop |
| Washer fluid De-icer or all-season, approx. 1 gal Top off the reservoir while you are at the cowl and test the new blades wet. | Consumables | shop |
| 13 mm socket and ratchet 13 mm 6-point socket, 3/8 in drive Only needed if you are also removing a wiper arm from its spline shaft, not for a blade swap. | Recommended | shop |
| Torque wrench 3/8 in drive, 5-80 ft-lb range To retorque a wiper arm nut if an arm was removed. | Recommended | shop |
No difference by engine or trim. 2.7L turbo, 5.3L, 6.2L and 3.0L Duramax trucks in all cab and bed configurations use the same 22 in driver and 22 in passenger hook-mount front blades, and none have a rear wiper.
| Wiper arm-to-transmission shaft nut (13 mm) | verify in the service manual |
| Wiper blade-to-arm hook connector | No torque - snap-fit plastic latch |
The 22 in / 22 in hook-type front blade sizing and the tab-release procedure are consistent across all 2019-2024 Silverado 1500 cab styles and engines; double-check the length against your old blade or the parts-store lookup before you buy, and treat the wiper arm nut torque as unverified.
Both sides take a 22 in blade with a hook (J-hook) arm connector. Because driver and passenger are the same length, you can buy two identical blades.
No. A small flat-blade screwdriver or needle-nose pliers to press the plastic release tab on the hook connector is the only tool, and often you can do it with a fingernail.
Usually leftover wax or road film on the glass, or the blade not fully latched on the hook. Clean the windshield with an ammonia-free glass cleaner and an isopropyl wipe, and tug the blade to confirm it clicked into place.
No wiper service mode is needed. Turn the ignition on, switch the wipers off so they park at the base of the glass, shut the ignition off, and the arms lift clear of the cowl easily.
