I have a 88 deville and i was just wondering how do you go about setting the climate control i mean do i push warmer to get the heat to cut on or do i have to click cooler till it comes on sort of like house thermostats
Push the heater button until it gets up to the temp that you want. These controls have proved to be problematic and the first thing a dealer will tell you is he has to order that control. I have fixed them, by taking them out and using a electronic cleaner and spraying the unit out completely or using conpressed air to remove dust that can be the problem.
If this does not fix it, get one from your local bone yard or find one on flea-bay and replace it.

PCM is the Powertrain Control Module. If you use the fan down button it will scroll through the different systems ACP ICP TCS etc. The PCM is the one you want to worry about though. Pushing the fan up button will select the pcm. Then it will give you options from there. The PCM controls ignition, shifting points, and a whole bunch of other related things.
Code 88 shows to not really mean any problems. Most of those years of cars have a small valve to control water flow. Make sure your heater core is getting water, and the fan runs. If not, check fuses and the control switches for heat/cool. With that switch they installed, wires may have been cut or spliced.
I ll try again. the dipstick is under the air filter housing -driver side front.
Just loosen the clamp around the air hose attached to the carbureter, pull housing slightly towards you and lift up.
Also, to check the codes on your car, turn the ignition on, (not running), and push the off button and the warmer button on the climate control section. the codes will appear in the information display by the speedometer.
The paths through your climate system are controlled by blend & diversion doors that are controlled by your settings and actuated by vacuum 'motors.'
If you live in a hot climate, you may have cracked vacuum hoses which can cause the kind of random air temp and mix you are having.
If you have never had any maintenance done that involves rubber products, it may be time to do it.
Ralph, Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change. FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out. This is very common on Cadillacs and Buicks. Charlie PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.
u either have vacuum leak on the lines running from ur climate control that directs air over the heater core or the climate control its but my guess its ur lines come off or crack its one those probs seeing it is easier to figure out
