Hi, I just bought a 94 Q and there is practically no power steering. The reservoir is full. The A/C also blows only warm air. I added refrigerant to it but no luck. The compressor kicks on when I put the A/C on auto but not manual. I did the diagnostics in the manual but it showed nothing.
Also the console switches for the windows aren't working.
Any help would be great.

Re: 1994 A/C blowing warm and no power steering (cr506)
How much did you buy it for if you don't mind?
Did you know of these problems existence before buying?
Have you checked the fuses and relays?
What is the smell/color of the Power steering fluid?
How many miles on it?
What was done to it for maintenance?
How are all the belts are they hooked up and good looking?
Does the drivers window go up and down?
Is the lock switch pressed down? (The master window control near the shifter controls all 3 window and the one above the left rear window controls the lock feature.)
You said you ran the A/C Diagnostic as stated right?
What was the code you got at the end?
Look at the EL section of the Factory Service Manual AKA FSM and look for Body Control Module Diagnostics.

Re: 1994 A/C blowing warm and no power steering (ppastos)
It was $1600. I hadn't planned on buying it but my truck is dying and I need something to get to work and back Monday.The window lock switch is not pressed down. All the windows work at each door switch except the rear left doesn't want to roll up without pulling it up.
The car has 149K on it. The steering fluid looks and smells ok and the belts are all in place.
I don't remember the last code I got. 51, I think. I followed the manual directions and didn't come up with any bad codes other than the 25 but I was outdoors in the sun.
I haven't checked any fuses or relays yet but I will tomorrow. The windows aren't as much of a concern for me but I don't want to cause further problems running with no pwr steering and it's way too hot here to go without a/c.
It also has a rough idle but I have been reading every post I can and I'm going to try the things I've come across to try to fix that.

Re: 1994 A/C blowing warm and no power steering (cr506)
What about the pump is it making any noise?
Does the steering feel any easier to turn at a dead stop or while driving?
I would say the the motor is bad.
What about the master switch do all the windows work for there?
Do you have a warranty from the dealer or was it a private sale?
When you say OK ,You mean not burnt and looks red right?
Why didn't you inspect the car before buying it to make sure everything works?
Did you look at the under carriage to make sure that the dust boots are in good shape and not ripped?
Or at least look for any major rust or obvious things?

Re: 1994 A/C blowing warm and no power steering (ppastos)
It was bought at auction and what I went there to get sold higher than I wanted to pay, so no, I didn't inspect if first but the steering problem was disclosed and I have no problem changing the motor myself but I don't want to if I don't have to. I didn't know if there were any other causes associated with these cars.
Each window switch at the individual doors work. I can roll the right rear window up and down from the center console but that's it. The other two do not work at the console.
The steering fluid looks like it should but I will certainly recheck in the morning. The pump makes no noise whatsoever and the steering is hard and acts the same whether at a stop or at any speed.
I know nothing about these cars except what I am trying to glean from this forum and all the posts I'm reading. It seems to be and okay car save for these few problems.

Re: 1994 A/C blowing warm and no power steering (cr506)
The window motor is very simple I think its just 3 or 4 (10MM) screws not rivets holding it in place. the door panel is very simple as well.
But these cars are best bought when You have given them a though inspection so you know what to expect. (Usually according to Q45Tech estimates it take 3-5K to restore these cars to OEM Assembly line quality sometimes more or less.)
The fact that the other two don't operate from the master switch could me the switch is bad. (There are 2 setts of switches 1 on each side).
On the power steering issue I am stumped. but How hard is it to turn the wheel?
I think that it could maybe be the rack.
The best thing you can do is call dealers around you and give them your VIN number and ask for the service history.
Also Did they provide a Carfax report or can you obtain one?
Also on the trunk does it say Q45 or Q45t or Q45a?

Re: 1994 A/C blowing warm and no power steering (ppastos)
The trunk says Q45. The steering when turned is jerky. It will turn but hit some hard spots. It is not easy to turn. It makes no difference at a stop or any speed. It can be turned but you have to use both hands and put in some effort.
Any idea on the air conditioner? I am going to run the diagnostics again today.

Re: 1994 A/C blowing warm and no power steering (cr506)
I ran the diagnostics again on the a/c and it throws no error codes.
as far as the steering, the pump seems like it is working but I think it may be the rack, the boots are torn and are likely full of dirt, etc. Would this cause the problem I am having?

Re: 1994 A/C blowing warm and no power steering (cr506)
A contaminated rack mechanism certainly won't help.
Have you checked your AC compressor clutch operation?

Re: 1994 A/C blowing warm and no power steering (maxnix)
The compressor works in auto mode but if I start the a/c in manual it doesn't kick on. I'm hoping it's a minor electrical problem. I don't know though.

Re: 1994 A/C blowing warm and no power steering (cr506)
On the A/C I really think its a relay or maybe even a fuse.
Re: 1994 A/C blowing warm and no power steering (ppastos)
I checked the fuse in the fuse panel and also the relay in the engine bay. Are there any others that I need to check?
Re: 1994 A/C blowing warm and no power steering (cr506)
Can anyone help with any info?
Re: 1994 A/C blowing warm and no power steering (cr506)
Has anyone had similar a/c problems?
Re: 1994 A/C blowing warm and no power steering (cr506)
I had a weird AC problem a while back. Seems there is something in the system that occasionally gets caught in a valve and the AC blows warm. When the stuff clears the valve, the AC blows cold again.
If your compressor clutch engages and stays on, then you need to check the pressures in your system. Spend the money to have a shop diagnosis the system, unless you know a lot about AC systems.
If the clutch will not engage, then you have to figure out if its electrical or because the freon pressure is low.
Once you know what's wrong with the AC its much easier to work on it.
