90 accord a/c prob by 90coupegak

2 part question guys-1. a/c condenser fan fuse keeps blowing so I replaced the condenser fan motor to no avail, it seems to happen (after the ac is on and the fan has worked for 5 minutes) with a slight jolt to the rpms as if their was a vacuum leak. Also 2. the a/c was ok at 75-80 degrees but at 90 the car is a sweatbox, I tried to charge it with new style refrigerant as i've seen it work on other cars but attempting that just made the front and firewall connection pins start leaking. I covered them with the plastic caps and now there's no cold air whatsoever. Ohh by the way the belt starts squeeking at takeoff w/ the a/c on but goes away in 2nd gear/higher rpms. Heeelp, any input would be greatly appreciated. thanx.

You'll need a good air conditioner guy to answer this question, and to look at your vehicle. The belts squealing, suggest that the a/c compressor is bound up too tight and putting too much a load on the belts. No cooling, would suggest too much, or not enough freon. It's actually the difference in pressure across the orifice (ie. the flow thru the orifice), which creates the cooling. If the low side pressure isn't low enough, you don't get the flow you need. Not low enough low side, can be cause by an orifice letting too much thru, too much freon in the system (high side doesn't have enough room to allow the low side to be pulled down), or the compressor not good enough to be able to pull down a vacuum..
 
Not enough high side pressure, is either a bad compressor, or orifice too large. Too much high side pressure, clogged orifice or bad pressure switch not turning off the compressor clutch.
 
I've never switched freon types (or heard of anyone doing that), that seems like a disaster in the making.
 
I'd get it to a good a/c guy. Expect charges for a purge, perhaps a new compressor (expensive), perhaps a new orifice (cheap), perhaps a new accumulator (medium $), and a refill with the correct freon. Pressure switch if needed.

I idid the replace from freon12 to r-134 a month ago. Not me, a mechanic, he vacuumed the compressor,clean it, clean valves, nuts, everything that could be cleaned . Put new lubricant, an adaptor that goes on the freon valve next to the radiator top so you can connect the new freon r-134a canister. put new R-134 and I have AC again... He told me to let the car run for a day and then put more gas. I got the "artic" canister with the pressure gauge on top..and I went all the way to 35 Psi If I recall well (half way on the full zone on the pressure gauge that come with the canister) so far it has been working fine.

Hi kiawah,
          now you are scaring me... did he miss something ? I can see bubbles in the receiver drier tanks, which was not replaced.
 
any suggestion?

Sorry, I thought you were the original poster who was still having the a/c problems, and had just done all of that work to the a/c. I didn't page all the way back, just replied to the reply.
 
If anyone paid to have all of that work done on it, and was still having problems, then take it back to the mechanic who did the work to fix it right. You don't want to have to pay for all of the freon evacuations and refills.
