I would suspect the alternator. A low voltage will cause this with some electronic instrument clusters. Get a voltmeter and check to see that the voltage on the battery when the car is running is higher than when the car is not running. A good battery may indicate around 13 volts when fully charged, but while running an alternator will run higher voltage often greater than 14 volts. Be sure to bring the idle up while testing for running conditions.

There are numerous things that will cause this problem. If the check engine light is on, have the codes checked to see if there is a problem the computer has found to cause this issue. Even without the check engine light on, there may be a code stored. You can also do a visual inspection under the hood for any disconnected hoses causing vacuum leaks. These are the best places to begin with diagnostics

If your thermostat is staying open then it won't get hot in the cab,if the heater is bad,it will leak and fog up the window,another cause could be the blend door is stuck close,or the valve is stuck close and antifreeze can;t circulate thru the heater core.When you first start your car does the thermometer on dash go up then cone down,if it is then thermostat is good.

replace the crank sensor

There are other problems if you could get it to autozone some how there are error codes that could be read from the ECU Are you getting fuel to the fuel rail? You could try some gas on the air filter and see if it would fire. That would confirm a fuel system problem.

Pull up the diagnostic trouble codes. Please Check the following areas: 1. ECM power source circuit and ground circuit. 2. Crankshaft position sensor 3. Camshaft position sensor 4. Ignition system 5. ECM 6. VC output circuit More over check the ignition confirmation signal on number 2 wire while cranking the engine. Thank you for visiting Fixya.

Is there battery voltage at the vent valve solenoid ? Does the PCM turn it on ?

Get bigger wattage bulbs fitted,or check that the dimmer switch is turned down low.

Your selector door is stuck. These are operated 3 ways Vacuum actuator Line could be disconnected or crimped or actuator is bad Electric Bad connection, Cable cable clip unhooked from door Door is under dash passenger side Hope this helps Mike

The battery light indicates, when lit, that the charging system (alternator), is not supplying enough power to run the vehicle and thus is draining the battery of power. Under normal conditions this should never happen. Have your charging system checked.

Your actuator is bad on the vent door, that switches from cool to hot. some units have several of these, some only have one

Check passenger side, under dash, make sure any loose linkage is actually attached to the baffle levers. I had this happen. Passenger accidently kicked the linkage off and suddenly we had no heat. It was seriously cold inside. Mechanic showed me the linkage disconnect on passenger side under the dash right under the glove compartment.

Could be a wiring problem or throttle position sensor or the DC motor that controls the throttle position. P0511 Toyota Idle Control System Malfunction

under the dash on the drivers side

which one, accessories, or cam? oops cam is CHAIN> accessories drive belt:

1. make a drawing of routing.
2. remove tension via adjuster or tension-er per FSM
3. remove belt
4. attach new belt per #1
5. set tension to spec. stated in FSM. some are set real tight.
6. done.

wow toy shows route on parts page, nice note 2 belts on some engines http://www.oemtoyotapartsgroup.com/a/Toyota_2003_Echo1500CC-16-VALVE-DOHC-EFI--AUTOMATIC2-DOOR/_52014_5774050/V-belt/160867-1605-141460.html so when the mech opens hood, he looks for the tension method first;. (a real tensioner device or is it just the alternator slides. etc. this is first. they used 3 alternators that year. power steering pump adjuster a/C compressor adjuster. we look and see that in about, 1min flat. so do that first. there are some engines with stand alone tensioner devices some are automatic others are manual set. the FSM covers all this if serious about DIY, why not buy one or log into alldata.com for 15 bucks and read.

check the wire to purge vsv. it has to be broken

It should stay on a few minutes than go off, does it go off after a while?
