  A: In order to replace the accumulator in the hvac system, first, use the a/c refrigerant recovery, recycling and recharging (ACR4) system (J 39500-8) to retrieve refrigerant from an a/c system. Remove the nut and cable of the positive Battery Cable from under the hood fuse block. Remove the negative Battery Cable. Then disconnect the hose of the evaporator from the cover of the accumulator and park it aside, then remove the cover of the accumulator. Then, pull the a/c compressor hose and the evaporator hose from the accumulator, and finally, pull the accumulator out of the housing. For installation, it is recommended to fill the new accumulator with the right quantity of refrigerant oil, then fitting it into the housing. Check the seal washers for damage before reinstalling the a / c lines and hoses and replace any damaged seals as needed. Mount the evaporator hose and nut to the accumulator and tighten the nut with 20 n.m (15 lb ft) and a/c compressor hose and nut with 20 n.m (15 lb ft). Connect the accumulator cover, and also the hose of the evaporator into retainer. Connect a jumper cable to another, properly charged and running automobile (other color) positive (red) one to the positive (red) battery post, jumper cable negative (black) one to battery post of the bad vehicle. Start the working automobile by turning the key to on without starting. The bad automobile should start and then be driven to a shop for diagnostics. Remove the jump cables after the car starts. 20-30 min will give the battery a 90% boost. Lastly, add charge to e-c system and check for leaks with electronic halogen leak detector (J 39400-A).
