Question about 1992 Chevrolet K1500

1 Answer

A/c problem The a/c indicator on my heating and cooling display began flashing today. My a/c has never worked since I bought the vehicle, but I put 2 cans of freon in it on Friday. It blew cold air for 2 days and now the light is flashing and it stopped blowing cold air. Is it the compressor, condensor, what?

If the compressor is not engaging then you probably have a leak somewhere.The light is more than likely tied into the pressure switchs and ecm.So it is flashing to let you know there is a problem.ie,low on refrigerant.Charge it up and put dye in the system.Then use a strong black light to find where the dye is leaking...Good Luck!!!

My car cut off several times today, after display the following message engine reduced, car slowing down.


the engine goes into safe mode when information is transmitted
to the control hardware of the engine/gearbox that there is a fault somewhere on the vehicle that has been detected by the sensor
system The act is performed to prevent more serious damage from happening than would occur if the engine was left to function at full power.
The cause should be indicated by a code that can be read through a scan of the vehicle's OBD, (ON BOARD DIAGNOSTICS,) Without access to this code it is difficult to say whether your malfunction is related to heat affecting the car.
The likelihood is that something has been exacerbated by the weather conditions but that the heat is not the cause. Something else will probably have been going on. previously that has worsened with heat.
The engine is obviously hotter in such conditions .....the engine runs hotter....the cooling system might be at it's limit.
Fuel evaporation might be taking place that might cause the sensors to meter functions less efficiently than might otherwise be the case.
Whatever....you should have a dealer perform a diagnost scan of the OBD so that you can obtain the code or codes necessary to identify the cause

Possible, with rad cap off, let vehicle idle until coolant fan comes on then shut vehicle off for 30 minute cool down. Top up rad, install cap and drive and recheck heater operation and any overheating.

2wd vs AWD


Page 13 of owner's manual says:
AdvanceTrac
(if equipped):
Illuminates when the AdvanceTrac
system is active. If the light remains
on, have the system serviced
immediately.
AWD locked (if equipped):
AWD
Illuminates when all wheel drive
LOCKED
(AWD) is engaged/activated. If the
light continues to flash, have the
system serviced.

Page 224:
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with an All Wheel Drive (AWD) transfer
case. With the AWD option, power is supplied to all four wheels
automatically with no need to shift between two-wheel drive and
four-wheel drive. If your vehicle is equipped with the AdvanceTrac
stability enhancement feature, you can change AWD modes, if desired,
by selecting AWD options through the message center.
For the lubricant specification and refill capacity of the AWD transfer
case refer to Maintenance and specifications chapter.
If your vehicle is equipped with AWD, a spare tire of a different
diameter than the road tires should never be used. Such a tire
could make the vehicle difficult to control as well as result in damage
to driveline components.
Utility and four-wheel drive vehicles are not designed for
cornering at speeds as high as passenger cars any more than
low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.
The following sections, Normal operation, Autolock operation and
Disabling AWD, apply only to vehicles which allow the driver to change
AWD modes through the message center.
Normal operation (vehicles equipped with AdvanceTrac
During normal operation:
• the AWD system is in AWD AUTO mode (AWD LOCKED will
illuminate in the message center for four seconds when you first start
your vehicle). The AWD LOCKED indicator in the instrument cluster
will also come on.
• AWD AUTO mode can be overridden by pressing SETUP in the
message center. When you first press SETUP, AWD <AUTO> will be
displayed, then if you press RESET within four seconds of pressing
SETUP, AWD <LOCKED> will be displayed. AWD <LOCKED> provides
power to all four wheels constantly which allows you to operate your
vehicle in severe winter or off-road conditions such as deep snow, ice
or shallow sand. It is not recommended that you use AWD <LOCKED>
on dry pavement.

Page 225:
• AWD <LOCKED> can be cancelled by pressing RESET in the message
center. (The AWD LOCKED display in the message center will then
turn off and the display will return to AWD <AUTO> for four seconds
when the shift is complete.)
Autolock operation (vehicles equipped with AdvanceTrac
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
• the AWD LOCKED indicator light will illuminate in the instrument
cluster and AWD DISABLED <LOCKED> will be displayed in the
message center.
• AWD LOCKED will be displayed in the message center for four
seconds and a warning chime will sound. This condition may clear
without any action being taken by the driver.
• the AWD LOCKED indicator light in the instrument cluster will turn
off when the AWD system cools down.
• When the system is sufficiently cooled down, AWD AUTO RESTORED
will appear in the message center for four seconds and a warning
chime will sound.
Disabling AWD (vehicles equipped with AdvanceTrac
When a problem is detected in the AWD system:
• the AWD LOCKED indicator light in the instrument cluster will flash
eight times every two minutes in the message center.
• The message center will then display AWD DISABLED for four
seconds, then SEE OWNER'S MANUAL. A warning chime will also
sound. The warning displays and chime will continue until RESET is
pressed (which will clear the message from the display).
• AWD LOCKED can still be engaged by pressing SETUP (the message
center will display AWD <DISABLED> LOCKED), then pressing
RESET. The AWD LOCKED indicator light will illuminate in the
instrument cluster and the message center will display AWD
DISABLED <LOCKED>.
• To disable AWD, press RESET. The system will go back to AWD AUTO
mode momentarily, then the AWD LOCKED indicator light will flash in
the instrument cluster eight times every two minutes. The display will
then show AWD <DISABLED> LOCKED for four seconds and then
turn off.

Page 226:
• If a serious problem occurs with the AWD system, the AWD LOCKED
indicator light in the instrument cluster will flash 10 times every two
minutes. The message center will also display CHECK AWD and a
warning chime will sound. You can press SETUP to check the status of
the AWD system (which will display AWD <DISABLED> LOCKED),
but the AWD system will be disabled until the system is serviced.
Driving off-road with truck and utility vehicles
AWD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
When driving at slow speeds off-road under high outside temperatures,
use 1 (First) gear when possible. 1 (First) gear operation will maximize
the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.

Your problem is leaking head gaskets or a faulty water pump. Check your exhaust tail pipe for black pungent prestone odor. This is an indication of head gasket trouble. Have your cooling system pressure tested. Good luck!

Unknown 2007 Toyota Camry Hybrid Button


The ECO HEAT/COOL button of your hybrid functions to reduce the consumption of electricity thus, a reduction of fuel consumption. An indicator 'ECO' appears on the air conditioning display to indicate that the mode is on. Of course, with the ECO HEAT/COOL on it'll take longer than the usual amount of time for the temperature to reach its normal or standard set temperature.

Your ECO HEAT/COOL mode won't function if your temperature control is set at 'LO" or 'HI" or if the air flow is in the "floor/windshield mode" or "windshield mode".

Hope this helps.

Car requesting oil even after being filled up.


This message does not mean the engine is low on oil, it means the oil change is due. if you have added oil, it may mean it is now overfilled. This could cause as much damage as low oil, VW have a system on the vehicle that tells you when the vehicle requires servicing, the next message should be inspection 1. these are the VW service schedules. They are worked out on mileage and the way the vehicle is driven. Take the vehicle to your local decent repair shop and get the oil and filter replaced, and remind them to reset the service indicator. After this all will be well.
