#401 of 527 Spark plugs and heat
Jan 03, 2006 (2:38 pm)
I have a 1993 ford aerostar (3.0L). I was thinking about replacing the sparkplugs in it myself. Could you give me some advice on how I can access all six(6) plugs?
Also, there is a problem with the interior heat. I recently had the heater coil, water pump and the thermostat replaced. Before those items malfunction the interior heat worked. Now only cold air blows out.
Any advice on the above problems?

I pulled the front blower motor today. Pull it straight out against the condenser, then when the fan 'clears' the housing, pull the fan towards the front of the van. Exxtremly tight squeeze, but luckily everthing in the rea moves a bit. I found lots of leaves packed against the heater core. Vacuumed the box out. Get more air, but still hasn't cured my initial problem. Can't find the flapper control to direct air tp the vents or defroster. Suspect a vacuum line leak.
#403 of 527 Flashing Dash guages
Jan 22, 2006 (9:34 pm)
I've got a 91 Aerostar that I simply Love. The Transfer case went out a couple years ago, and I parked it. The battery never went down, and it started right up after the two years. However, when it started, the dash gauge indicators (Its digital) goes through each one of them flashing on and off one at a time. The Van ran just fine though and I thought it was some sequence the computer was going through. I replaced the transfer case (the flashing continued) and the van ran just fine. Then after about 50 miles, it sorta just chugged, coughed, sputtered, then just died. Now it won't start at all. Any suggestions? Thanks!

thnx alot for the help,
#405 of 527 blower motor high only
Feb 06, 2006 (10:21 pm)
I just bought a '94 Aerostar and a rat had apparently made a nest in the air filter compartment (discovered when I went to change it) and in the blower motor and heater core area. I had to take it all apart to clean it out (lots of weeds and straw etc.) and after re assembling it I now have no low, medium, or higher medium, but only the highest setting on the fan works now. What did I do wrong? Also the rat had chewed through both of the vacuum hoses which is probably why the air only blows up through the defrost vents regardless where you turn the switch. I can take that in to get it fixed I guess but I'd at least like to get it working like it was before I cleaned it, if possible. Any suggestions? Thank you.
#406 of 527 no blower on first two settings
Feb 08, 2006 (8:19 pm)
My problem is close to the same as bangsong's #405, except no rat:
'99 GMC Sierra 1500. Blower/fan does not come on for first two settings, then comes on for settings 3,4, and 5. Pain to have to keep turning it on and off when it gets too warm in the truck. Any suggestions?

This is Bangsong, who had the rat problem and the no lower settings on the blower.. I have good news. I was able to fix it myself once a guy at the shop pointed me in the right direction. He showed me the part that was responsible for the various settings on the motor. He then let me go without charge to the auto parts store for a new part. I was unable to obtain the part at three different stores so I got an idea. I removed the part myself from the fire wall (two screws)and jumped around passed the offending resistor and it worked. Look for the wires leading from the blower motor to a box on the fire wall. If you remove that box there should be various sized springs on the under side of it. If you see a more conventional looking resistor among them, try jumping past it (wire from one side to the other to complete it's path around it) and see what happens. Or if you just don't want to do that, you can unplug that part and replace the whole thing and that should solve your problem.
Hope it works,

I'm wondering if when your parts were replaced, a vacuum hose may have either not been hooked back up correctly or not at all or was damaged. Those hoses control the valves that open and close the water into your heater core that the blower blows through to bring heat into the vehicle. If the vacuum hoses are installed incorrectly or are compromised, you will not open the valve to let hot water into your heater core and therefore no heat. The vacuum hoses are small, about 1/8 inch thick or so and if you need to replace any section of them, clear plastic tubing at the hardware store works great. Get the size that will tightly fit over the existing hose and complete the circuit. They will usually be color coded to keep from becoming hooked up wrong so check that as well.
Hope that helps,

If you have access to a lift, it's much eaier for yout back. Otherwise jack the car up and let it sit on stands. Make sure you have Ford or Autolite double platinum plugs plus some copper anti-seize (for the plug threads). It's a good idea to change the cable at this time too. (Use Motorcraft or Autolite only). Remove the front wheels and the well cover (located inside your 'star; between the driver & pasenger seat, right on the floor, below the radio). You sgould have enough room to change the all plugs. Access from underneath. About your heater problem, could the mechanic mistakenly connect the in to out and the out to the in? Look at another 'star to compare the hoses? If he installed the thermostat correctly? You can get a Chilton book to see if it hook up correct?
