    Does the a/c button blink on and off when it gets hot? How does it shift? The a/c compressor may be starting to sieze and causing drag.

Need miles - need type of auto transmission.

For now - check the fluid level and if the mileage is over 100,000 take it to a professional and have them give you a hands on diagnoses. Try two places.

Ac not cooling blows hot on both sides. how do i know if compressor is kicking on?

Don't forget the DCCV. those act funny (not ha ha.) you can pinch the middle heater hose to stop hot coolant from entering cabin This will narrow down your issues and if cool air cycles you have diagnosed the problem

My nissan quest first began to run hot only when the air conditioning was on. After a couple of weeks of riding without ac, it began to run hot even with the ac off. We've replaced the water pump and...

have a local mechanic do a pressure test on the cooling system as i think that a vehicle this old could need a new head gasket as they do deteriorate with age especialy on vehicles around the 98 to 2002 era with that funny bonding material that was used

Shifting hard and sometimes slow shifting at times like a slipping

The first thing is to check your fluid level while its running and hot.If its dark in color or smells funny change the fluid and filter.If your light comes on it will be the transmission solenoids.

I have no power on a/c control ford f 150 2007

The A/C is ran threw the transmission computer are you having problems with it shifting funny? if so check all fuse in the inside of the truck then check the fuses in the engine compartment, if you don't find any blown fuses buy a AC connector and hook up one wire to ground on the battery and one to positive on the battery se if the clutch kicks in if it does try starting it and see if it gets cold if it does then it's the AC computer that has a problem like a pinched wire between the pan and transmission. Do not run a hot wire to the AC connector be sure to purchase one so you don't blow the transmission computer it costs $300 plus labor. it it does not run then pull the low pressure switch plug on the receiver dryer looks like a aluminum tank insert a paper clip into the plug then try it again if the ac comes on and cools then you have a bad pressure switch, it costs $10.00 and can be replaced without losing refrigerant then unhook your spare power connector and hook up the original hook up to the compressor and replace the low pressure switch it should work then. If it does not work get back to me and I will give you some other tests to check it with.

Unable to get my 2003 chevy blazer to start. has been acting funny. the hot air has been running cold and takes the ac a long time to get cool. the engine runs hot.

get a mechanic to have a look ,water level low hence the heater is cold and ac taking a long time to cool because the fan isnt starting up when ac is turned on ,Sounds like your fan is playing up and you may have cooked the head gasket??

1999 Sable quits shifting when it gets hot

How do you know it's getting hot ? What is the Temp gauge showing ? Do the cooling fans work ? Have it checked for trouble codes an scan data checked .
It was however the correct thing to do in changing the fluid and filter - that's the first suspect. No no it wasn't , the correct thing would be to take it to a qualified repair shop . Hooking up a professional type scan tool an viewing data , inputs to transmission control module , ECM/PCM - engine computer etc. The control module controls shift solenoids -which shift the transmission . You could have 1-2 shift solenoid shorting when getting hot . View scan data is the only way to see this problem .

Ac does not work

it sounds like the main control that's in the dash where you control your hot and cold the a/c may be dieing out on you. You may need to replace that unit.
