Hello any one there?
Expert:  Marty replied 1 year ago.

Sorry for the wait I was stuck on another call.

Customer: replied 1 year ago.
Can you help me with this problem
Expert:  Marty replied 1 year ago.

Fuse #5 and #19 in the rear fuse box next to the battery are for the PSE pump.

Expert:  Marty replied 1 year ago.

To reset the pump you would remove both fuses for a few seconds.

Expert:  Marty replied 1 year ago.

Let me know if you need anything else.

Expert:  Marty replied 1 year ago.

If the fuses are good and the doors do not lock with the remote or with the button on the console you will need to replace the PSE pump.

Customer: replied 1 year ago.
Ok I'm trying it now
Expert:  Marty replied 1 year ago.

Ok

Customer: replied 1 year ago.

Customer: replied 1 year ago.

Expert:  Marty replied 1 year ago.

Fuse #5 is a 25 amp fuse. Fuse #19 is a 40 amp fuse.

Customer: replied 1 year ago.
Ok
Customer: replied 1 year ago.
Ok here is one problem number 4 has a 25 and 5 have a 30 and in between it is a 10
Expert:  Marty replied 1 year ago.

As long as all of the fuses are good you are fine.

Customer: replied 1 year ago.
I just took out the 5 and 19 and the fuses are good
Customer: replied 1 year ago.
Will this reset it if pump ok
Expert:  Marty replied 1 year ago.

Removing and reinserting the fuse resets the pump. If it doesn't work then the pump is bad.

Customer: replied 1 year ago.
Ok I'm putting them back in
Expert:  Marty replied 1 year ago.

Ok

Customer: replied 1 year ago.
I do hear anything other than the back light coming on
Customer: replied 1 year ago.
I just tried the key and doors and trunk will not open
Expert:  Marty replied 1 year ago.

If nothing works when using the key or the switch on the console you will need to replace the pump.

Customer: replied 1 year ago.
Where is it located
Expert:  Marty replied 1 year ago.

The pump is right there next to the battery in the foam box.

Customer: replied 1 year ago.
Ok what is the average price for them

Thank you for all your help in this matter. I'm willing to pass this website to my friends and family
Expert:  Marty replied 1 year ago.

Sorry for the wait, I had to leave to drive home. I'll reply back later tonight with a price on the PSE pump.
