1994 Ford Extended 1 Ton Van Low Miles Florida Van

Ford E-Series Van. Runs fine. Was a Headstart bus for a local county. Ford actually lists this vehicle as a school bus. It has a tow package and low miles. I recently had the timing chain replaced and I fixed the a/c and heat unit however the a/c unit vapor locked in the defrost position, which means in will still defrost the windows if needed. Sometimes the temp gauge doesn't work so I had a mechanic hook up a different gauge, it never worked, but the truck has never run hot as long as I've had it. Last time I had the truck out the transmission o/d light was flashing and the truck went in and out of gear but then it was fine... I checked the transmission fluid and it is clean and full so it may be a sensor??? The truck has a brand new battery, good tires(new in back) and a good strong engine. I will require a 100. deposit with paypal within 48 hrs and the truck paid within 7 days.
