Welcome Tim: What is this vehicle would help so please add that and any history of why you are working on it at all.
Lost without some info like,...

[Tom Greenleaf]

Ohm checking a clutch's coil you can do off vehicle totally and should find one that reads closer to about 4.5 +/- a little. 8.2 is way too high and 2.5...

[Tom Greenleaf]

So true - connections even early are a weak spot. Chase down which one loses continuity if need be when so and where. Not preferred is to poke wire...

[Tom Greenleaf]

Hmmm? Part look up didn't help if this really has a dozen connectors? Suggests multi-function run by ECM. Noted it was said known working relays didn't...

[Tom Greenleaf]

OK - sorry - the long thread is just harder. Now question is if that relay puts OUT to the clutch presumably next in line does it get out of fuse box...

[Tom Greenleaf]

Sorry if a repeat and parts look ups can be a way to see what relays are there to do what can be helpful. They can be tested off car and show good and...

[Tom Greenleaf]

Yes x 3 now for the clutch. Skipper and all, some Toyotas and other hung on to manually adjusted belt(s) even this late so check that as Cusser said....

[Tom Greenleaf]

It would be better anyway but from not working this diagnosis both Cornbinder89 and myself is almost sure. Do check for how strong a replacement is said...

[Tom Greenleaf]

It works with "natural" air flow but not with this clutch you said was working correctly and about can't be. If viscous oil/thermostatic type...

[Tom Greenleaf]

One of us is misunderstanding something as your pressures and think you meant "static" pressure just isn't possible.

Hope chart...

[Tom Greenleaf]

Again - I just have this gut feeling it's low now shows that by pressures and will be just ducky when right charge is in it for how long isn't known if...

[Tom Greenleaf]

Suggest AGAIST changing condenser making this unknown for capacity plus if you can get cool enough air with what you have what is there to gain? More...

[Tom Greenleaf]

Sorry to bug you, just some trivia on Model Year 1968. A couple laws went into effect that model year. Powered side marker lighting not just reflectors....

[Tom Greenleaf]

Just FYI - I doubt any OE set up is meant to really see that at a vent temp as it's just pushing it for freezing up around there. Small cabin area recirculating...

[Tom Greenleaf]

OK - 68 Vette. 1st year for a Mako (sp?) body with the highly tilted radiator and however your condenser fits in?

Here's why you charge...

[Tom Greenleaf]

Welcome. First off need to know just what this thing is now and type of A/C would help having an expansion valve set up or accumulator.

...

[Tom Greenleaf]

Lost with this: How can you produce 42F vent temps and not cool the interior? Windows left open? Is this the large 4 dr. cab with front A/C ducts only...

[Tom Greenleaf]

If you want to try pipe insulation is cheap enough for a test or just feel the temp of the line how much it warms up after the "O" tube. I...

[Tom Greenleaf]

Hmmm - does the clutch work at all or somehow seem weak? Funny but not a joke it's listed in stock for a heavy duty one not the OE one suggests it's...

[Tom Greenleaf]

Good thought. Was compressor new or a reman job?...
