Working on a 97 Caravan. I have no power to my evap purge solenoid, and egr solenoid and vac. Wiring diagrams shows the power is from a fuse labeled PTC 1. From the drawings the PTC fuses seem to be on the junction block under dash in a row over the relays. They look like flat thin square ceramic capacitors. Does any one know if I can replace these?
Yes it runs, I had codes for evap purge and egr. Both fed by same fuse. I had no 12v in "key on" position. When I installed an inline fuse from the "key on" power at PDC and fed the purge solenoid it solved my problem. Cleared codes and never came back. THanks
