My 2000 dodge durango has front and rear ac so where does the feont and rear expansion valve go??

 

usually, the rear txv is bolted to the rear evaporator...follow the rear a/c lines to where they go up through the floor of the vehicle and you will find the rear txv.

to find the front txv...follow the front a/c lines to the firewall...the lines should bolt the the txv at the firewall.

 

Front expansion valve is on the firewall. Rear one is under the car right ahead of the b pillar on the passenger's side, nowhere near the rear evaporator that's in the ceiling.
