1992 cadillac seville,I have truble with the climent control,when i start the car outside temp shows -- for temp and inside temp shows 85,when i try to lower the temp i get to about 78 or 79 and then it shows -- for inside temp too,it changes to defrost and blows very hot air and no matter what button you push it stays on defrost max heat. Thanks for any help.

225 F equates to 107.22 Celcius
normal operating range for engines is 85 c(185F) to 98 C (208 F)
100 C is boiling so 212 F is maximum temp anything over is excessive and requires attention

It is on the passenger side just off the glove box insert which you must remove.

These are early automotive electronics, its starting to show its age, a bad sensor, a corroded connection ect,ect. 22 years old, surprised a computer can last that long

If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541

A strut is a combination coil spring with the shock absorber inside. From what you describe, the shocks need replacement.

Check for deteriorated vacum hoses located behind htr & a/c control panel and in the engine compartment.

Sounds like your vacum control modulator and or your vacum hose that leads to your modulator might be off, loose or deteriorated possibly. Check for this.

good luck.

sounds like a temparature sensor problem - mixture is too rich to start hot. try starting it with full throttle - if it will start after 15 seconds of full throttle and cranking the temp sensor is definitely at fault - you wont flood the engine doing this only give more air to the engine.

Inside the trans, you will need to remove the pan to replace it.

did you test the motor from an outside 12 volt sorce? or did you plug it in the car wireing? after you got it in and found it did not work, have you test light the power wire for motor in car to see if its got good light or if its weak light. There is a chance you got a bad motor. or its not getting full power from car wireing. I believe thies heating systems work thru the ac systems. i'am gussing is a climent control heating.

have you tried putting the door key in the door lock and turning to the right this should disable the alarm
