SOURCE: 2000 GMC Jimmy will not start

The oil presure switch does have some bearing on the problem but my suggestion is to change the coil. I had a the same problem with an astro van. I changed everything that you have described and it fixed the problem just for a little while and then all of a sudden did it again. I changed the coild and the cold start swithch and never had the problem again.

Your transmission is electronic, it read's the the speed sensor from the yoke and relay's the information to the ECM which tell's the servos in the transmission acivate to change the gears up or down with the engine out put.

Hv/ac not working


Check pressure of refrigerant 134. Pressure maybe low so the compressor clutch will not kick in. Refrigerant are available in most automotive parts store. Just make sure you do not over charge the system because it gives you the same indication.

What does it mean when the ac button lights are blinking the ac buttons-ac and circulating button lights blink continuously and you cannot shut them off at all this just began after the car wouldnt...


it is needing to be calibrated because of dead battery.i cant remember for sure but i think you had to push rear wiper and recirc buttons at the same time and hold them down a couple of seconds. engine has to be running and at normal operating temp. lights will flash and vents will change heat to cold etc. if it fails any test the lights will just keep blinking untill repaired and recalibrated.

Instructions on how to turn air/heat on in 2003 mitsubishi galant


All those buttons normally are on the center concole. The heat/air knob turns to the red for heat, the more its turned in the red the hotter the heat blows. If your talking about the AC air, that should be on the knob that lets you chose the fan speed, just push it in to turn on the AC a light on the button may come on to let you know its been activated. the Rear Defrost is a single button, i think with 3 wavy lines top to bottom also in the center concole.

AC & Rear wiper switch button indicator lights blink


The procedure for re-setting the HVAC control panel on a 1998 Dodge Grand Caravan follows:
With ignition on but not running
1. turn knob to air vents
2. turn fan knob to ON
3. temperature setting on COLD (2X) {I have dual temp controls}
4. hold top(rear wiper) and bottom (rear wiper with wash) buttons pressing down together until all the buttons cycle through (this will require 1 to 2 minutes of continuous pressing)
I learned this from a very helpful local Dodge service adviser

Where is the low pressure switch for my Honda Odyssey 2003 AC ?


The A/C pressure switch is located in the high pressure line (the skinny one) on the passenger side of the engine compartment just under the fuse/relay box. The switch has three functions: <28 psi, the switch opens to protect the compressor from lack of lubrication. >220 psi, the switch shifts the radiator and compressor fan to high speed. >455 psi, the switch opens to protect the compressor seals. Check to see if you have any powertrain DTC's first. A faulty engine coolant temp sensor can cause problems with the compressor clutch relay. If the radiator and compressor fan come on with the A/C on but the compressor clutch does not operate, check the compressor clutch relay. You can also obtain Heater control panel diagnostic trouble codes (DTC's) by turning the ignition switch on. Then turn fan switch off. Press recirc button to select recirc air. Press and hold recirc to turn off recirc air but this time continue to hold the button down until recirc light comes on for two seconds and then goes off. If there is any trouble, the recirc light will then blink a code (if no trouble, the light will remain off) 1 blink = problem in air mix control motor circuit. 2 blinks = a problem in mode control motor circuit. 3 blinks = a problem in evaporator temperature sensor circuit. (this one could be a factor in your case) Turn the ignition switch off to end the test.

AC/Heat Fan runs continuously and Rear end roaring noise


Sounds like the wheel bearing on the right rear hub may be defective, that would cause the noise if the tires are ok. As far as the fan goes not sure this isn't working as designed.

Blinking lights after battery replacement


Solution: The remote key entry system is waiting for you to push the "Unlock" button on your keyfob to sync up the car's receiver and the keyfob's transmitter. Just push the keyfob button and the lights will stop blinking.
