It may just be that the headlight one is bad, u need to pull the fender liner and check for 12v.

Suggestion
What it happened to mine, was that they were unused for so long, that the water make a kind of paste inside the pipes and it was needed to clean all the ducts and replace the washers.
Inspect without removing the reservoir, the decision is made

After removing and inspecting without removing the reservoir, the decision is made to save this project for another day (maybe).

Suggestion · Original poster
A buddy did some searching and read that replacing the battery (1500 miles ago) causes the DME to forget that the washers are there; meaning that a dealer needs to re-flash the system.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The 1999 996 Cab I just bought is so clean that little things like the headlight washers not working are on the to-do list. No, it isn't the biggest deal in the world to me, but it is something that isn't correct, so let's fix it. A buddy did some searching and read that replacing the battery (1500 miles ago) causes the DME to forget that the washers are there; meaning that a dealer needs to re-flash the system.
This sounds a little bizarre, but for a first post on this forum, it's all I have so far. Anybody have a better plan than dealer re-flashing?
Right
Question. Does the pump on the driver's side fender sounds when you activate them? What it happened to mine, was that they were unused for so long, that the water make a kind of paste inside the pipes and it was needed to clean all the ducts and replace the washers.
Good points. The lights were ON, and no sound at all coming from the pump. I know that we didn't check for current after he read that post about re-flashing, so it will be done today. With both lights out (again) I can apply a little bit of air pressure to the hoses and see if a bit of soap placed on the pissers creates a bubble.
Checking for 12V will be done as well.
The windshield wiper washers work, so the question is whether there are two washer pumps, or are both windshield and headlight washers operated off the same pump? If so, a blockage?
Yes there r 2 seperate pumps. It may just be that the headlight one is bad, u need to pull the fender liner and check for 12v. It seems to happen on these cars.
Not so, maybe two pumps with every car that has headlight washers (maybe), but the vast majority of cars don't have the rally washers...or need them. After removing and inspecting without removing the reservoir, the decision is made to save this project for another day (maybe). I've learned enough to know that either the pump or the relay are bad, and not worth replacing, IMO.
