93 Truck AC Parts

[MrMarty51]

Taking the truck for a run with the A/C turned to max.
IDK how often the compressor clutch should cycle.
The indicator lamp flashes on/off with each cycle.
Does this appear normal ?
Sorry @dbrannon79 for jumping into Your thread.
I know You have posted more about the functions of A/C systems than anyone in the forum, since I been here.
A video clipper.

That seem to be cycling very fast! curious as to what your pressures are doing. might be a tad low on 134A.

I’ll wait until I get some cooling issues dealt with, check pressures, then, possibly throw some 134A at this thing.
Thank You very much for the reply.

I would try to not run the AC until then. with it short cycling, if low can starve the compressor of oil and cause premature failure.

I didn’t notice the fan kicking in at the higher temps, nor when the clutch was kicked in.

This video clip was before the engind had heated up.
The AC was on the run position and the indicator lamp is illuminating every time the compressor clutch kicks in.
The over heating is in the other thread about using oil and such.

Sucked Near A Quart of Oil, Temp went to 210.

Thank You very much @JayTheCPA Went to WM this morning and picked up a 5 gal bucket of T-4 15-W40 Rotella. I’ll quiz NAPA on the bypass oil filter and get the number. I will also search out a source for the FRANTZ oil filters and order in a half a dozen of those. Now time to get to work. Will...
