Windshield washer fluid is not spraying in the front. Checked fuses and replaced pump, but still not spraying.

When you turn the pump on, do you hear it running?

I suspect you don't hear it at all and if that is the case then we have a relay or a TIPM issue.

The washer pump relay is fed by the headlamp washer relay as they both operate when you clean the windshield.

So, let's start with checking the relays and even jump them and find out if the washers work.

If they don't then we could have an issue with the TIPM or even the switch.

So, we will have to get into that part of it and check the relay to find out if they are being grounded by the TIPM when you press the switch.

However, let's get to that next because the likely cause is a relay issue.

Let me know if you have questions. Thanks
