Car Forum / Driving, Maintenance, Tuning / 4x4 Cars / June 200599 GMC Yukon Rear A/C problems
Went to the dealer the other day to find out why my A/C wasn't working...estimate is for $1700 (Canadian)+ taxes. ouch. Yukon was stored winters, but the lines are leaking and the fittings going into the rear evap are leaking as well. I got prices from the local GM dealer, parts are for 4 lines (the replacement ones split in the middle) and the rear evap. Is this something a backyard mechanic could do over a weekend and then take the system in go get charged again? Tony wedgeindy@hotmail.com I just replaced the Compressor and accumulator on my 99 Trail Blazer, I didn't have any problems. I brought it into the local shop afterwards for a leak test and refill. I say go for it. > Went to the dealer the other day to find out why my A/C wasn't > working...estimate is for $1700 (Canadian)+ taxes.

Make sure you replace the reciever drier while you have it apart and add the correct amount of oil to it and for rear evaporator. I would also suggest you replace orifice valves while you have it apart. They are less than 10 buck and easy to change when system is not charged and they have screens in them that sometime plug up with metal flakes and reduce the orifices effectiveness. Sorry to be a total rookie at A/C.... Is the receiver/drier also called an accumulator? The dealer listed that I needed one of those too and they're $500 Canadian. Where are the orifice valves? How may are there? Where do I get the oil? How do I know how much oil to add to the accumulator?

The Orifice valve is located right inside the fitting this is the input to the evaporator ans ir held in place when feed line is connected to it and is east ro change. The rear unit may have a Orifice in same place or a thermally controlled unit that generally does not need replacing unless it is bad. As far as oil amount when you buy after market parts they usually come with instructions as to the amount to add for each replaced component. 1) The receiver/drier is called an accumulator on some cars. 2) Not sure where to find your orifice valves 3) You can get the A/C oil at almost any Autoparts store and you may be able to ask them how much oil to add 1-4 oz, the more parts your replace the more oil you will need to add. Otherwise the person topping up the A/C could possible add the oil for you it can be expensive to buy in small quantities.
