always toward the engine

change plug wires $30 change fuel filter$20 change air filter$20, Replace one thing at a time and see if there is any difference.

use a volt meter and check the voltage with the engine off. should be 12 volts then check again with engine running it should be 13 to 15 volts if no then the pcm is at fault. the voltage regulator is inside the computer control and you will need to have it checked out at a dealership. if bad will have to replace the computer on van to correct the charging system. hope this will help!!!

A/C relays on the driver side fender under the hood .

Do you see the fluid coming back out? Can you describe where?

Sounds more like a stuck high beam relay. Daytime running lights module appeared sometime after '99 year. The relay should be in the fuse compartment. Pull it out to check that it is only the high beam that is on. Pull the low beam relay and place in the high beam location. If it turns on the high beams again, then try the dimmer switch to see if they go out. If that has no effect, then there is a sneak path somewhere that is turning the relay on.

How do the hoses going into the firewall on engine side under hood feel ? They should be reasonably same temperature. If one is hot, and other is quite a bit cooler, then you may have blockage still in core. If they feel close to same (hot) then blend/air door may be stuck. Can you hear things moving under dash when switched from cold to hot, and hot to cold? Does the air coming out get hotter if you rev engine a little and hold it there?

it sounds like it is limp mode,
if the computer see a problem in the transmission it will keep it in first gear so you can limp to a shop for repairs.
check to see if your speedometer is working if not the problem is the output sensor

sounds like your timing belt could have skipped a tooth, get the timing checked.

Good chance your water pump is shot! Might need to flush entire cooling system, which includes the Heater Core. Let me know if I can help you with more details if needed.

check the ground on the computer the wires sometimes come loose and cause this

You must first remove the steering wheel. You may be able to work around the turn signal switch. Insert the key and turn the ignition to the "run" position. It will slide out of its mounting hole now. If it does not come out easily push the locking pin in with a 16 penny nail or other pointed instrument.
