Checking Relays (and fuses)

a honda, vauxhall? is that an engine swap???
all spark plug tips,
please do say, what end of spark plug is oily.
some cars have spark wells. and the top is full of oil.
do tell..... id need the engine displacement (or type ) to answer well.
oil on tips is bad.
what transmission> you have?
oil on tips can be from:
1: bad rings or valve guides.
2: PCV stcking in raw oil to induction (hoses routed wrong on PCV?)
I say one engine so filthy the oil head drains were blocked and the PCV was sucking oil.
3: A/T transmission ATF fluid, from the vacuum modulator (bad)
4: bad head gasket (do a compression test)

and the inane
we have what is called JibbyLube joints. (spelled wrong)
and these dorks, use high pressure air to blow in new engine
oil into the engine. and blast oil past the PVC in to the induction.
nothing but bad bad bad, can happen. even hyralocking a piston. (bent rods , horror)
or oil burning for 3 hours until the intake cleans out. and big white cloud out the tail

i think i hit them all.
no, cracked block or head.

Great tip! Thanks. I inspected my relay and the contacts definitely showed signs of arching. Another cause of a flashing AC button light is a loose connection (male to female plug) at the compressor. I had my timing belt replaced and the Toyota mechanic failed to plug it back in... the light would be on for about 5 seconds then start to flash for this as well.

I think you should go for manual first after that it would be easy for you to solve your problem. I had visited this site past 2 months before for my vehicle and find it quite helpful may be you will also get something useful here

Mini ISO Relay is a TYPE of relay. Your vehicle uses 2 types of relays; Mini ISO Releays and Micro ISO Relays. They are located in several locations throughout the vehicle. I do not know what you mean by "Transmission Relay" What, exactly, are you trying to fix?

REMOVAL & INSTALLATION Start the engine and allow it to reach normal operating temperature, then turn the ignition switch OFF. Disconnect the negative battery cable. Open the hood and locate the O2sensor connector. It may be necessary to raise and safely support the vehicle for access to the sensor and its connector. NOTE: On a few models, it may be necessary to remove the passenger seat and lift the carpeting in order to access the connector for a downstream O2sensor. Disengage the O2sensor pigtail connector from the vehicle harness connector. NOTE: There are generally 2 methods used to mount an O2sensor in the exhaust system. Either the O2sensor is threaded directly into the exhaust component (screw-in type) or the O2sensor is retained by a flange and 2 nuts or bolts (flange type). WARNING To prevent damaging a screw-in type O2sensor, if excessive force is needed to remove the sensor lubricate it with penetrating oil prior to removal. Also, be sure to protect the tip of the sensor; O2sensor tips are very sensitive and may be easily damaged if allowed to strike or come in contact with other objects. Remove the sensor, as follows: Screw-in type sensors: Since O2sensors are usually designed with a permanently-attached wiring pigtail, it may be necessary to use a socket or wrench that is designed specifically for this purpose. Before purchasing such a socket, be sure that you can't save some money by using a box end wrench for sensor removal. Flange type sensors: Loosen the hold-down nuts or bolts and pull the sensor out of the exhaust component. Be sure to remove and discard the old sensor gasket, if equipped. You will need a new gasket for installation. Perform a visual inspection of the sensor. Black sooty deposits may indicate a rich air/fuel mixture, brown deposits may indicate an oil consumption problem, and white gritty deposits may indicate an internal coolant leak. All of these conditions can destroy a new sensor if not corrected before installation. To install: Install the sensor, as follows: NOTE: A special anti-seize compound is used on most screw-in type O2sensor threads, and is designed to ease O2sensor removal. New sensors usually have the compound already applied to the threads. However, if installing the old O2sensor or the new sensor did not come with compound, apply a thin coating of electrically conductive anti-seize compound to the sensor threads. WARNING Be sure to prevent any of the anti-seize compound from coming in contact with the O2sensor tip. Also, take precautions to protect the sensor tip from physical damage during installation. Screw-in type sensors: Install the sensor in the mounting boss, then tighten it securely. Flange type sensors: Position a new sensor gasket on the exhaust component and insert the sensor. Tighten the hold-down fasteners securely and evenly. Reattach the sensor pigtail connector to the vehicle harness connector. Lower the vehicle. Connect the negative battery cable. Start the engine and ensure no Diagnostic Trouble Codes (DTC's) are set. Posting pictures next......
