Re: Bad start capacitor?
You can look at the start capacitor for signs of leakage. Also check to see if it is getting hot.
If you can get a replacement that's the best way to confirm it being bad unless you have a capacitor tester.
I think you said the compressor was getting hot. If it is something is stopping it from starting. There is an overload device which is about 3/4 " thick and 1" in diameter which goes bad but if it is bad usually the compressor is dead - - - won't even try to run. The overload is located near the start capacitor.
If the condenser coils are clogged with lint- etc. the compressor will also get hot due to not enough air flowing over the coils. This also will cause you refrigerator to not get cold enough.
I really think you have a stuck compressor. I have been wrong before so it is best to check the cheapest things first. I hope this helps you !

Try checking for a restriction in the system. possibly the catalytic converter. are the pipes before the muffler? you can smack your catalytic converter with a dead blow hammer a few times before you start the engine. you will hear a sound similar to breaking glass from inside the converter it's carbon build up. Start the engine and rev it up a little. If it was constricted the carbon you broke loose will blow on out. If nothing is restricted in exhaust you may have a bad exhaust valve on that side.
i have had luck using a flat bar on each side. get it in the drum and pull on one then the other and sometimes both at the same time. also open the brake bleader or crack the line. just keep inching it forward.
smack the starter a few times with a hammer. If its a starter issue it may free up.. Or you could jump the terminals on the starter. If it does nothing and you know you have 12v at the starter,, then the starter is frozen. Smacking it a few times will only confirm its the problem if the truck starts. Jumping the terminals will confirm you have voltage because it will spark as you do it if you use a screwdriver.
Also you have a ASD relay in the underhood fuse block. Rotate it with a another like the horn or ABS.
If the compressor is getting power and refuses to start it is likely stuck and smacking it with a rubber hammer may temporarily free it. It will ultimately need replaced. if there is no power the reason will have to be determined, start with the defrost timer... Eric
Compressor won’t Start
The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.
Remove the caliper, then give rotor a good solid smack with a large rubber hammer or a 2x4 placed across it for protection and a decent weight hammer. (use wd 40 around center and also through openings where wheel lugs come through.) I know...sounds really "high tech" but it works every time!
the compressor is stuck // locked up. the start capacitor may be bad, they have what is called a hard start kit for this problem.Or the unit may be old and leakage past the piston seals has bound the compressor. Or it could have stoped at ust that bad position where it can't get enough ooomph frmthe capacitorr to get it to rotate at this position. If you know somebody with a hammer drill, place a small 2x4 along the base of the compressor and vibrate it with the hamer dreill - this may free it up while you hear it hum. If not, you will probably need a hard start kit
Starter motor or solenoid is going bad or cables are corroded. Clean all cables if car does not crank have someone try to crank it while you "smack" the started motor housing with a hammer or a long solid rod (hitting the rod with the hammer as it rests on starter motor case). Hit it sharply a few times. If it starts, then the starter motor is bad.
