Maybe fuel pump...check for trouble code...if no codes check fuel pressure

hi, it should be on the side of the steering wheel under the plastic covers. if you are going to do the job yourself then i would disconnect the battery first and wait for 15 or20 minutes before you start any repairs. you don't need the air bags going off on you. google it first for more information if you can.

should be under the dash near the steering column or in the fuse box area

Have you changed the tires and wheels? If not check speed sensor on transmission!

Will the fan work on high speed ? Is fuse #12 in the instrument fuse panel good ?

Could be a number of things. Timing, fuel pump, crank or cam sensor etc.

Possibly faulty throttle position sensor. Also gooked up EGR valve assy, allowing unwanted air in at the base of the TBI unit, therefore making engine rough at low RPMs good luck

if it spewed out brake fluid then you have a leak the [manifold ] master cylinder will have fluid till you pump it out --no brake pressure no release

under vehicle passenger side where engine meets transmission almost inline with passenger wheel

To Remove:

1. Disable the SIR system. (See section on SIR Precautions)
2. Remove the steering wheel from the steering column. (See section on Steering Wheel)
3. Remove the steering column trim covers.
4. Remove the wire harness straps from the wire harness assembly.
5. Disconnect the multifunction switch/SIR coil assembly connector from the base of the column.
6. Remove the multifunction switch/SIR coil assembly lead from the wire harness assembly.
7. Remove the 3 pan head tapping screws from the multifunction switch/SIR coil assembly.
8. Slide the multifunction switch/SIR coil assembly off of the steering column.

Hope this helps. Be very careful where airbag is involved.

Sounds like you may have to change the fan motor itself.

This website www.reliable-store.com has the largest collection of repair, service, parts manuals of any vehicle on earth. Best website I came across for manuals.. Also have live assistance

My personal suggestion would be to go for these repair catalogs. I know this website reliable-store.com that I used to buy them from, and they have online it was very good manual. Go ahead, I bet.

Antena and cable are one piece, before you remove it connect a piece of wire to the old one so you can use it to fish the new one in.

Sounds like you have the wrong part should be OEM Be careful of after market

if it has the 4.3 liter they are famous for crank sensors going bad

i can help , kinda, i had trouble with my astro van door lock in the back , it is not connected to the electric door locks , turns out the thing was broke inside, i had to pry off the inside panel and reach inside the door itself to unlock it, this can be done without damaging the panel or trim but you have to unscrew some parts, and work it loose very gently, on the rest of it, well i have been having trouble with the door locks on my astro, i think its just a weakness in design on these guys

this is common the fuse is located in the fuse box but the common problem with these is the blower resisitor, this is located next to the blower and is screwed into heater box, a quick test is to check for power and ground to blower first and check fuses located under the dash on the driverside. also check under the hood in the engine compartment for another fuse/relay box hope this helps.
