Hey Fellas,

I have a 1993 F-150 with a new create 5.0 H/O, Auto Trans, and all that good stuff. My problem is:

When I turn off all the vent/heater/ect... hot air still blow from the floor vents. When I turn on the A/C on normal and MAX it blow out even hotter air. I hear that if you can jump the A/C pump that this will engage the pump to kick it. Well I did that but it still blow out hot air. I live in Wisconsin and freon is illeage i suppose. But are there any ideas or is this just a recharge factor?

Thanks in advance for all of your help!

Thanks for the information but do you have any thoughts on my problem? :-) I'm glad to have joined the forums!

 

The compressor clutch will not engage unless there is enough refridgerant in the system. If it's been converted to 134A, you can buy that at auto parts stores (even at Walmart) and try it yourself. If it is still R-12 then you will need to take it to a shop, as you need a license to purchase R-12 (and the stuff is pretty expensive).

 

Echo:
I think you had better have a lookie see at your blend door just to be sure.You need to put gauges on system and get both high and low readings.Don't use a jumper any longer than necessary.You didn't state if it has been converted to 134 or if any lines got cold when you jumped it.

 

I only tried to jump it for 3-4 minuets to see if the clutch engaged. The lines never got cold either. It's still the old R-12 style. Any idea on how much it could run?

thanks guys!

 

Hi well on my 1988 f 150 it cost about 100.00 for a recharge the guy that done mine only charged me 35 bucks labor rest was the R12 ......
Hope this helps............

 

Last I heard A/C shops were charging about $30-35 per pound for R-12 and you'll need about 3 pounds. How much the whole job costs depends on what components caused the leak plus the costs of all the troubleshooting and repair time. If the cost to repair including R-12 recharge approaches the cost of repair and converting to R-134A, then I'd go with the conversion. As a minimum, you're likely to need a few o-rings and a new accumulator plus a few ounces of refrigeration oil for a R-12 recharge.

 

I was wondering if there would be any benefit to take out the old ac system? I'd like to free up some room and get rid of the condensor. Would the create any electrical problems?


Thanks,
Brian

 

Don't think removing would make any electrical problems as long as you insulated ends of any disconnected wires. But, if it was mine and I didn't want to fix it I'd just leave everything as-is. If you decide to sell it at some future time, it may well be worth more to the buyer to have everything on it even though non-working. I really don't see any advantage to removing everything-you don't gain very much "room", you don't lose much weight, and the horsepower gain is negligible since the clutch is never engaged.

 

Get an Interdynamics R-134 changeover kit from your local parts house. Pep Boys here in Calif. had it on special this week for $29.99. Great price because it usually sells for $35 - $45. You get 3 cans of a freon, oil, leak sealer blend, hi and low side fittings, hose with a guage, and great instructions. Takes less then 20 minutes to changeover.

 

Does that kit actually work? I'd love to do this but I thought you had to change all the parts and stuff over?

Thanks, Brian

 

this kit realy does work and as far as changing stuff the kit i bought had adapters to go right on to my pre exhisting fittings then you just plug them on to youre lines turn on youre ac keep an eye on youre charge pressure with the one that comes with the kit and wallaaa youve got ac make sure you fallow the instructions they will tell where to find the correct hose to charge the system with this is very important . of course i had my system discharged of th old R12 first.

 

You must evacuate the system first, but it sounds like yours should be completely empty. I did my F-150 2 years ago and it still blows ice cold. Excellent kit, easy to install, and the 3 cans in the kit will fill your system.
