Looks like it is under the hood, passenger side firewall.

you need to state what the problems are that you are having with the a/c blower so we can try to help you

First, switch off ignition. (see image) you will see the blower unit. The resistor is screwed into this. Detach the electrical supply (see pic) then unscrew the faulty resistor. Install new one. This is for a 1998. But I believe it is the same

sounds like the wires to your fuel injector its a common problem on them melting make sure the wires are not touching! Replace as nessairy

There are a few different things that can cause your problem. When the problem is occurring, disconnect the alternator plug, start the engine and measure voltage with a voltmeter. Connect a test light to 12V, reconnect the alternator connector and back probe the brown wire with the test light. Check to see if the alternator charges else, replace the alternator. Also, you may have a faulty instrument cluster. If you need more help on how to repair your alternator I would suggest checking out this sites HowTo section http://www.buyautoparts.com/howto/

The battery warning light tells the driver the alternator is not charging the battery.

timing? if you've got gas and you've got spark, have you checked the crank/cam shaft position sensors? have you put a timing light on it to see if you might have jumpped timing?

Its usually in the side of your thermostat housing. has a 2 or 3 wire plug hooked to it

on that age it would be hard to find one i think it would be cheaper to find one already done used

probably not module if it restarted within a minute of dying if it smokes black it is most likely fuel system related possibly fuel pressure rewgulater also check coolant level in radiater could also be vacuum leak check egr valve

Did you check the fuses,or disconnect wiring plug at fuel pump,to see if you have power there,if not you have a broken wire some where.brad

Sounds like a bad ignition module. The module does two functions. It runs the ignition coil and also delivers the signal to the ecm to run the injectors. Sounds like it isn't putting out a tach signal.

The fuel pump may be corroded from the water. You can check it's operation by turning on the igntion a few cycles waiting a few seconds between and seeing if it runs every time [ the PCM will turn it on for a few seconds without the engine running], If it's inconsistent, then it may be the problem, but check the relay under the hood first.

This is for 4.3L V6

If you have the 4.3l, here you go

Hope this helps.

Did it backfire beofre you did the service? I'm guessing you have the wires mixed up.

Firing order 1-6-5-4-3-2, Distributor rotates clockwise

Hope this helps.

have you also replaced the fuel filter?
