I found the one in the engine bay on the drivers side. I am having problems with my 12v (always on) lighter adapters. The key on lighter adapter still works.

So I am looking for the fuse that supports the always on lighter adapters

Thanks,

Rick

One fuse panel on an 03, under the hood. As I recall you move the fuse from one set of contacts to an adjacent set to change from always on to key on or visa versa. Might be in your owners manual.

The key on outlet has a fuse, the battery outlet is a PTC, it is built into the PDC (fuse block under hood)

What is a PTC?

So what you are saying is there is no fuse associated with the Battery outlet?

It's kinda like a built in circuit breaker. Maybe there is a short in the system

Is there a way to reset the circuit breaker?

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?

No, they are not replaceable. I'm sure some energetic person would tear it all apart and try to solder in a new one but not made to replace.

that PTC also powers the control side of the fuel pump relay. Does the vehicle run?

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
