Have the vehicle scanned, I think you'll find that the coolant temp sender unit may be defective.Regards Johngee

Chevy 2005 tahoe z71 blows cold air in back but hot air in front


Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

When the weather is very cold (below zero) the car will not even try to turn over it wil only click at the starter and ignition no turn battery is fine never does this any other time. only cold, but once...


It is normal for batteries to lose a good deal of their power due to cold temperatures. If you want better starting power, try using a battery charger/maintainer overnight. It should charge at no more than 2 amps. The slow trickle charging overnight will charge and warm up the battery and allow it to develop full power for a cold morning start.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

1998 Catera will not start if it sits overnight in cold weather


It can be worn distributor cap/rotor or coolant temperature sensor.
To check it leave car outside, try to activate if it is not use the hair fan and worm up the distributor cap area
http://www.autozone.com/Ntt,distributor%20cap/shopping/allResults.htm
If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor:
http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c15280090338
and, if no help, spurk plug area.
Also good idea in cold weather use higher octane fuel or regular with octane booster or injectror cleaner added and ask the mechenic to put winter oil (less viscous) for winter time during oil change.
Good Luck
