Sounds like the evaporator coil, or a hose to it is leaking inside the car. Do you see water on the ground with the car sitting and the air on? Maybe the drain is clogged? Mold build up has clogged drain?

what year / model

unhook battery for 20 minutes both cables.

make sure the cam timing is correct

No easy fix, or override for that. You have to pull the inner door panel off and hot wire the window motor to get the window up. With the panel off, you can diagnose the problem, maybe a broken feed wire where it enters the door.

go to a local junk yard and pull the computers and the complte wiring harness out of a car with a vtec, your old computer will not work with that engine you need to replace all the electrical wiring harnesses

If you are carburator or fuel injection you should have a tach meter hopefully it works. Crank the engine does the tach slighty move this small movement tell us if you have spark. You state no spark at coil 3 item that wont allow spark to happen the magnetic pick up the ignitor and the coil itself.Or even the distributor cap itself. 2 main failure for no spark is the ignitor itself. and the magnetic pick up

Worn spark plugs, a defective coolant temperature sensor, or a defective auxiliary air valve [aka fast idle thermo valve] would be the first items to check.

Go to autozone.com and register. It is free, and after you do it, they ask you about your cars. Once you enter a vehicle into your "garage", you get to access an online repair manual for free. You can view diagrams and even print articles. They are not the most complete manuals i have ever seen (go with Haynes for that), but they are very good and completely free of charge. You are unlikely to get a better manual for free!

i hope this helps

On the 85 model the speedometer and odometer are driven by a cable. This cable must have broken and will need replaced. Check the speedo cable where it connects to both the speed sensor and the back of the gauge cluster to make sure that the little prongs on the end of the speedo cable are fitting into the matching holes on each end of the connection. sometimes it slips out and loses its connection causing the gauges to go dead. Last but not least if the cable is good the the instrument cluster will need replaced. The VSS or speed sensor is on the transmission, the cable connets to this and to the gauges. If it were me I would get a new sensor and new cables which is cheaper than having a mechanic work on this, if the issue is not fixed then the guages must be replaced and these can be found at salvage yards or on the net as many years are interchangable.

Hi.

Accessing that hose is a bit of a pain in the.... The hose is accessed from underneath the car. First you need to take off the air filter housing and the thermostat housing, thhen you finish the work working under the car. undoing the bolts that hold the the pipe and cutting or undoing thef heater hose and oil cooler hose (the hoses must be replaced afterward). Replace hoses and O rings keeping the hoses in place to finish the job.

Regards.
