Question about 1998 Chevrolet S-10 Pickup

4 Answers

A/C Won't hold a charge. I went and bought two cans of R134, and put them in my A/C, It blew cold, and I even went out to make sure it was still working a few times after I put it in. When I went to get in my truck tonight, The compressor just continued spinning and shutting off repeatedly, I guess you would call it short cycling? Before the compressor spinned for a long time and it was blowing cold, But it went back to it's old way (short cycling) within 6 hours of putting the refridgerant in. I put in some leak detection dye with the R134, and I can't find a leak... What else could it be? I'm actually trying to sell this truck and The A/C working is one of the top questions I get...

    I bought the cans of R134 and put them in my truck and it all leaked out on the same day. I don't know how to take off the dash to get to the evaporator... Does anyone know of where to find a how to on taking out the dash?

  • logiczero21 May 07, 2010

    Yeah, I did a little trial run of taking off the dash, I almost cracked it. I'll just sell it as is and knock the price down a couple hundred. Thanks.

Hi! Have you tried working on the thermostat? You may need to set it right till you get the perfect timing to avoid short cycling or may need replacement if no luck on setting. THe last resort will be replacing the compressor. Lets hope that its just the thermostat. HOpe this helps and have a good one!

    Yes its kinda painful taking off the dash just to get the evap. But its the only way to fix it and it will require lot of patience. Estimated time of removal is atleast 3hrs. work.

You wont be able to see the dye without a special filter mask. Even so the leak may be under the dash leaking out the evaporator. The shorter cycling is normal when the pressure is low and soon it will stop cycling when it becomes empty again. There a tool we use to sniff for a leak. The tool will beep when the sensor gets near the leak. We sometimes have a hard time finding the leak even with using the right tools. Most likely leak places are in the compresser and the evaporator or thru the bearing on the compressor clutch. Look close at the compressor and clutch area. If it looks wet or black sooty then thats most likely the leak. If you need to open open the system to replace a part then your only option is to have a shop perform the job for you since r134 will need to be vacuumed out and stored and then reinstalled with correct amount of r134 and oil. Also before they fill the system they put a vacuum back on the system to remove all the air and to confirm it will hold a vacuum. Then they fill it back up.
I know this is not what you want to hear but it is your only choice for repairing this properly. There is no way you can fix this without the proper tools. Plan on spending a few hundred bucks at the least. If you do not store the remaining r134 you will release it into the atmosphere which is very bad. You will also be throwing away a couple hundred bucks worth r134

    You cant proceed until you have the engine compartment first checked out. No use spending 10 hours removing the dash when the leak may be in the engine area. What the shop will do is put the fan on and put the sniffer down the vent to confirm the leak is in the evaporator before even thinking of taking the dash apart. If it is the evaporator once you remove it and replace it your stuck having to go to the shop. You cant just add 8 to 9 lbs of r134 with air in the system. It will be a waste of time.

    Your best bet is to have the shop diagnose this and vacuum the system. Then you can go home and replace the part. Then you will have to go back to the shop so they can confirm the fix before charging it up again.

If you can't see the leak then it's probably in the dash evaporator (or the pipes leading to it). You will have to dismantle the dash to access and replace it (if you're lucky you would have to solder it only).

The Evaporator is usually the issue for a leak and its in the dash. Its most likely why you cant find the leak. Jack up a corner or the truck and get under the vehicle find the drain for condensation and use the UV detector youll probably find trace of the dye there.

1999 acura cl wont;; hold a/c charge. have to put 134 in it


if it did not have r134 gas before DO NOT put r134 gas in now. The r134 runs at a much higher pressure and you need new condenser/evaporator and compressor to compensate for the high pressures generated. have an A/C technician explain it to you

A/c not blowing cold


It takes R12 from the factory. The charge ports are located under the air cleaner housing on the right side. You can see them, but to service them you need to loosen the air cleaner housing, two bolts, and remove it or get it out of the way. If you want to charge it, or just "top it off" yourself you can get a kit off of ebay that has the hoses you need. Some sellers won't sell the R12 unless you have a license. I bought the R12 off of a seller on craigslist and the hose from ebay separately and saved a ton of money because I know my car well. But if there's anything wrong with your car, I highly recommend taking in to a garage like Firestone and have them look at it and/or do the work. If you don't know the history of the car, it may have been converted to R134- look for any stickers in the engine compartment indicating this. You don't want to mix different kinds of refrigerants. If there are leaks, bad circuits or components, diagnosing or repairing an A/C system is complicated and an expert is going to have to work on it. Take it to Firestone, they can do R12. R12 works much better than R134. R134 pollutes just as much and even more prone to leaking so don't feel guilty about using R12. It's not worth the expense of converting it and you wont' be satisfied with the results because it won't get cold enough.

How do I retrofit my A/C in a 1990 toyota camry to 134A?


The way I did on an older car was to buy the "Easychill retofit/recharge kit" at WalMart. About $40.
You will evacuated the system (discharge current refrigerant) then exchange the low side pressure port with the one supplied in the kit. Then refill to about 50 psi using the charge hose and R134a supplied in the kit. While charging, have A/C turned to max cold and blower running, engine running. Hold can upside down and shake as it fills. Release trigger periodically on refill hose to check pressure guage on the hose in the kit. Very simple to do yourself.

Im trying to recharge my ac in my 1995 audi 90


buy r134 can w/pressure gauge at local parts or department store. Folllow directions on can as far as application. The valve only fits the low pressure line, so there is no way to accidentally attempt charging high pressure side. Unscrew cap, attach valve of r134, check gauge. if fully charged already, do not overcharge... won't cool better, only cause damage.

If my air conditioning condenser is damaged and the air conditioning system now fails to blow chilled air, is this a loss of Freon? If so its poisonous, so I am under the impression I should not attempt to...


Hi.

The freon is not poisonous. The gas currently in use is the R134 (no HFC's) replacing the old R12.

You can replace the condenser and then you have to charge the system with the right amount of gas and some lubricant.

A/c hot!


Possibly. Make sure you didn't overfill it. It will not work if there is too much R134 in the system.

If starting from scratch. Turn engine on with AC on Max. Add 1 can first, and the compressor should start to cycle and the air should begin to cool. Add the next and the compressor should run almost consistently. You should get cold air by then and you have enough R134 in it to work well. If that doesn't cure you, then you will have to trust their diagnosis.

REMEMBER. Do not hold the can upside down. Instead, keep switching the can from the 10 o'clock position to 2 o'clock and back. Holding it upside down will also lock up the A/C, as it is being filled with liquid, instead of gas. Liquid does not compress.

You have a leak. If the refrigerant pressure [amount] is too low the compressor will not turn on . And to see the leak detector dye you must use a florescent light.
The reason it repeatedly works, then stops working is caused by a switch that will inhibit the compressor from turning on with low refrigerant pressure. After it stops working the refrigerant makes its way through the system and builds up pressure at the low pressure switch again therefore allowing the compressor to work again.

Ac blows hot


If your compressor is working the low side should be 15-38 psi. If you have 100 psi that means the compressor is not doing what it should. Make sure the outer clutch is engaged with the pully. If not A/C system check should be done.
