Want this question answered?
Yes....try Hypertech or JET.
I believe it is located under the passinger side seat? At least on my 89 LXi is where it is
The electronic control module is located behind the right side of the dash board
My 89 Corvette which is also a C4 recommends 35psi on all 4 tires
If your 89 Celebrity has the 2.5L 4 cylinder engine the ignition module is mounted on the block below the intake manifold toward the drivers side of the engine. If your 89 Celebrity has the 2.8L V6 the ignition module is mounted on the block on the radiator side of the engine on the drivers side. Both are a bit of a pain to get to, but it is doable.
The book I looked in has some printing missing BUT it looks like the ignition module could be mounted below the steering column. It is in some Subaru's. Hope this helps.
no, the hinges are different and size
Turn your ignition to the on position. If an amber lite that reads ABS or Anti-lock comes on in you dash, you do have abs brakes.
RH under hood, between blower and evaporator according to diagram. The blower control module is most likely the culprit. It was on my 87 covette ,easy to replace but cost about $150.00
No. There are three different tops for the C4 Corvettes, 84 to early 86, late 86 to 88, and 89 to 96.
I have an 89 Delta 88 and if you have Electronic Climate Control there is a control module located just right(passenger side) of center at the firewall. It is in the same location as the blower fan resister assembly on a car with standard a/c controls.
If you remove the distributor cap and rotor you will see it bolted to the plate and it will have electric wires pluged into it. It will be on the right side of the distributor.
