My 1998 WIndstar has a constant door chime ring

SOURCE: I have a 2001 Ford

could be the anti theft. try turning the key backwards. then try to start it.

SOURCE: chime goes off

Open the drivers door and look at the hindge area and you will see a black rubber accordian tube between the door and the pillar.This is the protective cover for the wiring harness. Now take a screw driver and stick it into the latch that latches when u close the door and trip the latch. Now start up the vehicle and wiggle the black tube and see if you can duplicate the concern. If so then pull the cover back and inspect the wires for a broken wire. these models are bad for this happening.

I can't help with the chimes, but as far as the awful smell, try changing the cabin air filter. It's under the hood on the passenger side. Close to the wipers up near the firewall is a rectangle cover about an inch thick and about 12-15" long. Inside is a filter. It's very easy to remove and replace, and this fixed the funky smell in my van immediately.

Sound like one of the door jamb switches is bad. Try taking a pencil or screw driver and pushing in on each door switch. Push the switch beyond the "flush" point to see if the switch is just not fully closing.

SOURCE: where is the abs brake controller?

An anti-lock braking system, or ABS (from the German, Antiblockiersystem) is a safety system which prevents the wheels on a motor vehicle from locking while braking.
A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to continue interacting tractively with the road surface as directed by driver steering inputs. While ABS offers improved vehicle control in some circumstances, it can also present disadvantages including increased braking distance on slippery surfaces such as ice, packed snow, gravel, steel plates and bridges, or anything other than dry pavement. ABS has also been demonstrated to create a false sense of security in drivers, who may drive more aggressively as a result.[citation needed]
Since initial widespread use in production cars, anti-lock braking systems have evolved considerably. Recent versions not only prevent wheel lock under braking, but also electronically control the front-to-rear brake bias. This function, depending on its specific capabilities and implementation, is known as electronic brakeforce distribution (EBD), traction control system (TCS or ASR), emergency brake assist (BA, EBA or HBA), or electronic stability control (ESP, ESC or DSC).
