I have a 1989 olds 88 royale brougham that has me puzzled..Can't seem to figure out why My Climate Control won't adjust hot/cold. Done changed Panel & Actuator already and it's still n

Faulty shut of valve. Engine and water starts cold, after 5 minutes it is warming up. The heat 'off' control isn't working. It is a mechanical faucet, the heat is on all the time.

Here you go copy and past then click on the first picture. It's number 5. https://www.google.com/search?client=ms-android-americamovil-us&ei=59KZWYn7DcPymQG4yoOIDw&q=1987+oldsmobile+delta+88+royale+brougham+map+sensor+location&oq=1987+oldsmobile+delta+88+royale+brougham+map+sensor+location&gs_l=mobile-gws-serp.3...4920.20339.0.21667.21.21.0.0.0.0.406.5585.0j1j16j2j1.20.0....0...1.1j4.64.mobile-gws-serp..1.17.4932...0j0i22i30k1j33i22i29i30k1j33i160k1j33i21k1.dB-spKCclH4

Sounds like you have a Bad Intake Gasket

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.

YES. you need to take your battery to O'Reilly's, Autozone, Advance Auto and have the CCA's checked..(Cold Cranking Amps)..this is the only way to know if your battery is good..they will show you..get a new..enjoy...

There are many factors that go into a cars value. You best bet to get the best ball park figure is to google search NADA blue book or Kelly Blue Book. These companies specialize in determining the value of vehicles and are the industry standard when it comes to car value.

Once you are on there site you will enter several key important pieces of information like engine size, 2 door or 4 door, Royal or brougham, sunroof, what power option, Etc. and then give you the approximate values.

Off the top of my head you could expect any where from $1000 to $2500 depending on the condition. New brake, tires, or other repairs make no difference on the value of the car. Those are things that needed to be done although they are good selling points.

This could be caused by a faulty MAF sensor or an O2 sensor. Does the Check engine light come on when this happens?

I would check the crankshaft and camshaft sensors. I don't think the connections are wrong, they really only go on 1 way.

It's fuel injected! Tell me where you come up with flooding? It won't start on a cold day,other wise okey and runs well,I doubt it?

there is a blower motor control unit under the hood on the right side near the firewall, unplug this and it should stop running. normal problem for a lot of gm cars with electronic climate control
