I thought we did this to ***** the other day, but I see the question and all my research has vanished. Did you delete it? It is here and stated at 1/4HP on R134.
Tecumseh Product Co. TPA1380YXA 1/4 HP R-134 https://controlscentral.com/tabid/63/ProductID/326408/tecumseh-tpa1380yxa-tp104ar-003-j7-1-4-hp-r-134.aspx

to get an answer we need to know the make model year, engine size turbo etc because what you have given means nothing
Vin are vehicle serial numbers and that same make of vehicle can have several engine capacities depending on the manufacturers level of car finish( sedan --low hp super sports big engine hp)

Here is how most are laid out.

Have questions please let me know, Thanks Sea Breeze

I don't believe there is a standard value for a specific horsepower rating. I have serviced and replaced plenty of these capacitors and the manufacturers say it is important to use only the value that the motor is originally supplied with. I have not seen it correspond to horsepower directly. Some motors use both a start and a run capacitor and I've never seen them identical. Horsepower listed ratings can vary wildly if it is not directly listed on the motor spec label. I believe .5hp corresponds to about 6 to 8 amps at 120 volts.

Sounds like a blockage in freon lines or a freon leak.

It depends the model number, 452 BTU are 1/6 HP, R134a 776 BTU are 1/5 HP.

in 1986 it is r12 but you can convert to r134 which is a ton cheaper than paying for r12 you need a license to buy r12 r134 is right on the shelf at auto zone they also sell retro fit kits with everything you need to convert your system and they work very well

That looks to be a Tecumseh R134a compressor near 700 BTUs, close to 1/4 HP, rated at low pressure (-10 degrees F evaporator temperature)

You should see lines comming out of the compressor. follow them around untill you see a black or blue plastic cap that will be the system service port's you need to find out what is in the system from the factory before putting any in.I belive the 1989 fords had R12 and you need to get the system evacuated before getting a R134 retrofit kit to put R134 in it. unless you are certified to work on R12 systems. than you can buy R12 reclaimed ref. but the avrage person can not.

First I would make sure the compressor is running.

Unplug the Ref. for about 15-20 min, plug it back in and listen for the compressor to start. You will have to be behind the Ref to tell the difference between the compressor fan and the compressor. If the compressor clicks and doesn't run then the relay on the compressor should be replaced. If it runs then it is probably low on coolant.
