**TLDR:** Sun-baked **wiper rubber**, weak arm tension and clogged **washer nozzles** get checked before the first rain, not during it.

A wiper blade inspection at Route 66 Auto Repair in Upland checks the rubber, the arms and the washer system before you need them. Our long dry season bakes wiper rubber, so blades that looked fine in spring often smear or chatter in the first storm. We check the whole system, not only the blades, and write down what we find.

## How do you know your wipers need attention?

- Streaks or haze left behind on each pass
- Chattering or skipping across the glass
- Cracked, split or hardened rubber edges
- Washer fluid that dribbles or misses the glass
- Wipers that move slowly, park in the wrong spot or stop mid-sweep

## Why check more than the blades?

New blades cannot fix a weak arm spring or a bent arm, which let the blade lift off the glass at freeway speed. We check that each arm presses evenly and that the blade sits flat along its length. We also test every wiper speed, the intermittent setting, and whether the wipers park where they should.

The washer side gets the same attention: fluid level, pump operation and nozzle aim. Dust and tree sap clog nozzles here, which leaves you smearing grime across the glass. We also look at the windshield for chips in the wiper path, since blades can snag on them. Chips and cracks are handled by our [auto body and glass services](https://route66autorepairshop.com/auto-body-and-glass-services) team.

## How we inspect your wipers

1. **Look at the rubber:** Blade edges are inspected for cracks, hardening and tears.
2. **Test the sweep:** Each speed, the intermittent setting and park position are tested with water on the glass.
3. **Check the arms:** Arm tension and blade contact are checked.
4. **Test the washers:** Pump, fluid level and nozzle spray are checked.
5. **Result:** You get findings for each part and a written estimate if anything is needed.

## How pricing and timing work

The inspection price is stated before we check. Blades, washer parts and motor repairs are each listed on the written estimate. It is quick to add to another visit, such as a [vehicle safety inspection](https://route66autorepairshop.com/diagnostics-and-inspections/vehicle-safety-inspection) or an [annual vehicle inspection](https://route66autorepairshop.com/diagnostics-and-inspections/annual-vehicle-inspection).

## Frequently asked questions

### How often should wiper blades be replaced here?

Heat and sun age the rubber even when it never rains. Many Inland Empire drivers replace blades about once a year, ideally in fall before the wet months. We inspect them so you replace them when they actually need it.

### Why do my new blades still streak?

A dirty or waxy windshield, a bent arm or weak arm tension can all cause streaks with new blades. Cleaning the glass and checking the arms usually finds the cause.

### Can I use plain water instead of washer fluid?

Plain water does not cut road film well and can leave mineral spots. Washer fluid is made to lift grime. Use a type suited to your vehicle and the season.
