My windshield washer stopped squirting about a year ago. I finally got around to diagnosing the problem and found that the pump is dead. So a call to Lotus turned up a pump and wash bottle assembly for $96. That sounded a bit expensive so I kept looking for just the pump. This turned into a scavenger hunt since the pump does not seem to be a common part. I ultimately found a used one on eBay for $10 that worked great.
I’d like to share the various part numbers that I found in my search.
The original pump is GM part number 090586631
It has been replaced by GM part number 24439253
This is also used in the Saab 9-5 for the rear washer as Saab parts 90585761 and 4832895
Saab parts seem to be a lot easier to find than Lotus parts
