2004 Crown Vic - heater blower motor

Hello everyone,


I am enjoying my 04 Crown Vic. I got it for a great deal. I do and some small complaints and was wondering if I could get a little help. The problem is with the blower motor. It works on 1 and high all the time and only on fan speed 2 and 3 some of the time. I know other models have resistor cards but when they are bad it only works on high. (all the time)

any help would be great

Does this have climate control or a regular heater?

Good morning thank you for your reply.

It has just the regular heater.

As you have power all the time and ground or it wouldn't work on high. I would try a new resister the older ones had two in one so part of it could be failing.
Look along the firewall about the center on top of the heater case.

looking at your engine the relay is on the right end of your heater box just behind the right valve cover with 3 wires connected.

I got 2005 crown vic 235,000 milage on it i got new battri the alternator is working but but after four hours parking it drain the battrie/////
big headach every time jump cable

Disconnect the ground wire use a DVOM between the ground wire and the cable set to amps. Get a reading after the under dash lights shut off. Pull one fuse at a time until the drain goes way down. When you find the general area disconnect one item at a time until you locate. I've had an alternator drain the battery disconnect this to check this item. Sometimes a fuel pump relay will go bad and cause this. Normally you will have a small drain for clock and ect.

Your problem with the battery going dead after a few hours could be broken wires from the under hood wiring harness coming from the fuse panel and going down and looping across under the rad support to the computer and incar fuse panel.I would check that harness for broken or cut wiring .Ford is known to forget the wiring harness support bracket or putting a loop in the harness before it crosses the rad support giving a place for water and road junk a place to rot the harness.
