(SPOILER AERT--I am not claiming that the foil replacement is bad, just
looking for advice)

Installed the vanagon.com south Africa product. Everything fine, got my
turn signal indicators back immediately. No longer had to treat the
instrument cluster like a human brain to get it back in the van in working
order. Love the LED switchover.

But... not long after the install, the temp LED came on and stayed on. This
happened about every four times the car is run, and when it happens,
required going into the hatch and pulling the connector out of the sensor,
then replacing. Good for another four drives or so. May come on upon
startup, may wait until I am on the road.

Swapped out for a spare, new coolant level sensor. No luck.
Pulled the connector and shorted the pins. No luck.
Pulled the cluster, reset ll the T14 connector contacts. No luck.
Checked the ground. No luck.
Swapped the temp gauge with a known good one from a 1991. No luck (worth
noting that the gauge in the car had been re-capacitored by David B not so
many years ago, and had been working perfectly).

Contacted Vanagon.org, they are contacting the mfr. I am figuring the test
procedures they recommend are going to be above my pay grade. Any notion of
some practical tests that might localize the failure to something?
