SOURCE: 1999 plymouth breeze rom's running high

does it idle high also? i've had that problem, when i start the car (same as yours) it idles at 4.5rpms and after twenty minutes of driving for some reason goes to normal, i was told its a rpm sensor problem. good luck.

SOURCE: check engine lite stays on

If you disconnect the battery for 1 minute and reconnect it the check engine lite will reset. when you start your vehicle again the lite shouldn't be on unless the problem is still present. If the problem is still there the lite will come on again and you should take it in to a shop and have it diagnosed for engine codes and see what the problem is.
Try disconnecting the battery first though before you go spending great amounts of money on something that was probably just a minor glitch in the computer.

Bets of luck and let me know if this has helped you.

SOURCE: PLYMOUTH BREEZE 99 WILL NOT BLOW HEAT UNLESS ITS ON HIGH

It's your blower motor resistor that's shot. I just replaced mine. It cost $40 canadian and I replaced it in 10 minutes. It's located under the glove compartment. Just remove the blower cover (2 push pins) and there it is under the blower.

SOURCE: my car jump time

#1 are you sure it jumped time?#2 how do you know this? if in fact it has jumped time you will need to have the timing belt replaced.the average interval for replacement is 60,000-80,000.it is also a good idea to replace the water pump at the same time as it is driven by the timing belt.
