The switch sits right beside the compressor and has a lable "QP2-4.7G". The messures are 1"x 3/4"x 1 1/4'h . It has number "06 6" at the bottom. I have ordered this part # from several companies and all send me a three-pronged part and not a one-prong part. The parts they send me says QP2-4.7 on it, not QP2-4.7G. Where can I buy such part?

The klixson switch is located normally in beside compressor electrical connections sitting against body of compressor to ensure it does not overheat

has the car been it an accident in its history?
it could be that there is 1 coil broken of de spring. or that there is a problem with the balljoints. put the car on a flat surface and start messuring up everything left side and right side to find out where your hight differences come from.

You have fuses and relays . The fuses are or should br labled inside each cover if still there as well as on the fuse block itself, If not I can look under the hood of mine and tell you. The relays from left to right thats passenger to driver and numbered including the empty spaces as mine hase three on the right and two on the left with three emty slots in between. Now Olds seems to have kept this araingement for some time also my '98 88 has ABS as part of TCS but no relays there and diferent climate controls over the years it is posible you have more or less than are presnt on mine the complete list is as follows
#1 - AC compressor control for the compressors clutch
#2 - Horn relay
#3 - AC blower fan motor on, at low speed on the '98
#4 - AC blower motor off or high speed depending on year, not present on my "98
#5 - ABS pump relay ,not present on my '98
#6 - ABS Main relay also labled as pump relay for some years, not present on '98
#7 - High speed cooling or radiator fan
#8 - Low speed cooling or radiator fan

You have the right port if it fits the RECHARGE hose. If it's reading 130 psi, it might be way overcharged.
Did you follow directions and did the AC compressor clutch kick in? At that pressure,on the low side,the compressor shouldn't even engage.
To discharge the system if overcharged,you need for a shop to do it. don-ohio (:^)

If the problem is consistent in other windows besides strictly the keyboard it is possible that the capacitive touch panel is defective or has been damaged.

I would take a close look at the switch & take note of the following.

How does it attaches to the PC board?
How do the wires attach?
What is the physical size?

Then go to www.mouser.com or www.digikey.com and start switch shopping. If you look at the catalog view for the style of switch you looking for it is easier to find a replacement my visual cues, instead of part numbers.

Worse case scenario if it is simply switching the 2 attached wires, a different micro switch could be used & glued onto the existing board where the old switch has been removed.

Or.... you could simply short the 2 wires together to bypass the purpose of the switch, but the unit would always be on.

the low oil switch may not be set right may sure the arrows are pointing straight up or you can bypass the switch all together that's up to you.

Your answer will be under your hood,Check on the radiator brace on on the heater box assembly ,you will find a yellow or white sticker that give you that info.

As far as the heater damper goes, you will definitely have to get taken care of. Not sure if they are vaccum or cable type on that year. I am going to say that you need your ac recharged. If it is low the compressor will kick in and out. Another possibility is the control panel where the controls are. Good luck

Looking at the model number, it appears to be a 3 ton. (36,000 btu) Most all residential units are single phase and most all commercial are 3 phase. One way to tell, look to see if the compressor has a capacitor. 3 phase never use capacitors on the compressors as they are not needed. Some residential units have a "Dual" capacitor. That is, it has 3 terminals, 1 common, 1 for condenser fan motor, and 1 for the compressor. Also, this info should be printed on the unit's lable.
Good Luck and hope this helps.
