Rear washer pump stopped working

Front wipers and pump works. Pulled and cleaned wiper relays number 7317. Switched front relay with back relay on left side of relay box located under top radiator hose. No change. Rear pump cannot be heard when switch is pushed in for washer fluid. Checked number twelve fuse. It is okay. The rear wipers are working.
Is the culprit a bad switch? If so, how to test and replace? Thanks.

Probably a failed pump. There are two pumps, one for the front and one for the rear, remove the washer bottle and test the pump, manually.

I was under the belief that there is only one pump that feeds both front and rear glass. Am I incorrect?

I replaced the washer pump under the hood and still have no washer spray on rear glass when switch is actuated. But rear wiper works fine.

If there is a rear pump? Where is it located? Or is the multi-function switch on the dash that controls spray and wiper actions the problem?

Ready to pull my thinning hair out!

Sorry I was wrong, must of been thinking of a different version. There is a rear washer control relay in the aux relay box Number one. Its on the left had side of the engine compartment.

You misunderstood my question. I know there is a rear washer control relay.
Is there a rear pump? If so, where is it located? There is only one pump on my fluid reservoir under hood with two outlets. One for rear and one for front. Right?

Hi,

I have found the information you are looking for plus a couple of guides to show you how to do the testing.

Please recheck all fuses before you begin.

Here is a guide to check the relay as well:

Please let us know what happens.
