arch Posted May 15, 2009 Share Posted May 15, 2009 Hi, Where is the a/c accumulator in my car, I think it is under the dash, if so how difficult is it to replace. Arch Quote Link to comment Share on other sites More sharing options...
GuyTelefunken Posted May 16, 2009 Share Posted May 16, 2009 The GS has no accumulator. The system uses a receiver-drier, which performs a similar function. The desiccant material inside the receiver-dryer can be replaced. It is located in a long tube on the side of the condenser at the front of the car.

arch Posted May 18, 2009 Author Share Posted May 18, 2009 I have have been told the expansion tank is under dash in gs 400/99. What do I have to take off to get to it and replace or clean it. What is done when installing a new compressor. arch Quote Link to comment Share on other sites More sharing options...
GuyTelefunken Posted May 22, 2009 Share Posted May 22, 2009 The expansion valve is under the dash, on the side of the evaporator core. It is difficult to get to without removing the entire dashboard. The only reason you would need to replace it when replacing the compressor is if the compressor had failed in a catastrophic way and contaminated the system with metal particles.
