Bill, Tyvm. There is always that option, and the prices seem reasonable. I will try the cleaning method first.

Actually , you need to ever so gently spread the (easily broken plastic) ' wings ' over those ' pins ' then the switch will more or less fall apart on you , if you neglected to work over a terry towel , some tiny ball bearings and miniscule springs plus contacts will fall out , bounce once or thrice and never be seen again .
Once you have it apart , use de greaser (house hold products that are safe for plastics work well here) , with some brushes to clean out the amazing old dirt , grease and misc. crud that's in there .
Now use METAL POLISH to clean and polish the contacts until they shine , a new pencil eraser to clean the copper contact pins in the bottom of the open switch's body , then smear some Dielectric grease in there and learn to swear like a 150 year old Sailor as you try to re assembling it all correctly .
Did I mention the clean towel ? failure to follow this means you now have a nice clean switch missing a couple of non available parts....
Luckily these switches don't change much internally from 1981 onwards so any old Junk Yard switch should yield the parts you need to get it going again .
Tedious , delicate work I don't envy you on .

The white plastic part of my regulator was broken - I replaced it...Now my switch itself needs to be cleaned. Am planning to clean the switch, but having difficulty taking it apart There seems to be a small circular pin on the side. which I need o push in (?), but it is being very tough to push in. Should I soak the switch is something? Cleaning itself entails mineral spirits, I think, and then some lube.

A/C used constantly , I've been commuting in it since April 11th .
Diesel Kleen silver bottle used , no startron this time .
361 miles , the low fuel light has been on since yesterday , I drove it from l.A. to Pasadena and some errands then back to l.A. before tanking up , the new , clear plastic intake fuel screen was slightly cloudy again (crud from the bottom of the tank I assume) so I dumped in a quart of Startron and filled it to the very lip of the filler neck and parked it on a slight side slope to ensure the entire fuel sender & tube is soaking in the Statron over night .
28.4 MPG .
It's running quite well I might add , now has 344,XXX miles in it and is hands down the very best $1,500 car this Old man has ever bought and i've had more than most .
G'night .
Nate
