W124 1995 E320 fault codes 5 & 21
I pulled fault codes 5 (Exhaust gas recirculation inoperative) & 21 (Bad Purge Switch-Over Valve).
I pulled those codes because the CEL came on and I had no A/C in the cabin (nothing was coming out of the vents-just the heat from the engine) Are codes 5 and 21 interelated? What do you think should be my first course of action on my 95 e320? Thank you for your help in advance.... |

First step is to clear the codes and see what comes back. Also build the code reader and check the other pins for codes including pin 7 for AC.

Thank you... I erased the codes and I replaced fuse#7 (which it was bad) and so far no problems....

If code 5 comes back do a search for "EGR pipe".
