Re: Retro-fitting with a thermostat
If you have a wall or window unit you'll have replace the t-stat by the model number. If you have a central system you get a t-stat from a hardware store from $30 to $200 depending on model. I would recommend a digital t-stat because they are accurate +/- 1 degree where a mercury t-stat is +/- 10 degrees. either way they come with instructions and only take a few minutes to install.

DO A AMP CHECK ON THE CLUTCH , SHOULD BE AROUND 10 AMPS . IT MAY BE A BAD CLUTCH ELECTRO MAGNET .. SOUNDS LIKE A RETRO FIT JOB, YOU NEED TO RUN THE FAN SPEED ON LOW, THE WAIST COOL FROM THE EVAPORATOR COOL THE COMPRESSOR. IF NOT THE COMPRESSOR GETS HOT AND THE EXTRA HEAT BURNS UP THE COIL..
no way .. the lub used in r12 is not compatable with r134 .. and you cant mix the two refrigerants ...also if the system has been "dead" for awhile then its likely to have air/moisture in the system .. moisture is very bad .. it can cause internal iceing and can damage the system from inside (corrosion) ... you have to pull a vacuum to clear that stuff and to regenerate the "dryer" .. you should also wash out the system (sometimes dry nitrogen is used) ...then you have another problem .. if the r12 leaked out then r134 will leak even faster .. its a smaller molicule and needs a tighter system .. so your system would have to be repaired ..maybe hoses replaced ... even if you could do all that you are not permitted by law ... you have to be certified to work with r12 .. you cant just vent it to air ... it has to be reclaimed .. really strong penalties for violating that .. the moderrn equipment does all this .. even tests the system and automatically refills the proper amount .. thats a lot of work for $200 .. the automatic equipment does it much easier and safer .. you might find someone that will do it for less ... antique car clubs often have someone certified in this retro fit ..
To retrofit you need to change the condenser, drier, expansion valve and compressor. Generally these units take around 800 grams. Your best way to check is while charging, set the ac on low fan and feel the suction pipe(thick one) where it returns to the engine compartment. It will be cool, charge until it feels cold. That will be enough gas. You can get away with removing the old oil on the compressor, flushing it with 141b and refilling with same amount of polyolester oil.
Solids state fan controls don't work correctly with fluorescent bulbs. If you check the tail end of you remote's instructions it will say something like "Max light watts: 300 (incandescent only). So replace your energy saver bulbs with 60 watt "regular" bulbs to solve your problem.
