Can someone advise how ro pop off the white plastic grill over jets without breaking? One jet is just dribbling, the other barely adequate. I examined from underneath but it seems like access from above is needed. The wires are for heating, right?

When I've had that symptom on my vans it was due to the molded rubber Tee fitting under the jets that connects the plastic supply tubing. These rubber fittings deteriorate and crack with time, and then there is little or no pressure at the jets. a tube comes from the pump to one jet, then crosses to the other. The one just dribbling is probably the downstream one, and I'll bet the Tee on that is leaking badly.
Even knowing about this I've done visual inspection and not found it, thinking it was clogged instead.
