Check and make sure that your power steering fluid is topped off. Could possibly problems with your power steering pump. Mine does the same and the fluid is full. I just keep an eye/ear on it. If it continues to get worse than it could be the pump going out. If the fluid is allowed to get too low, it could possibly get air in it affecting both the "feel" of the steering and making a noise.
The head gasket is allowing compression gas into the water jacket. Did you have the head ground flat before installing it on the head gasket?. Was the old head gasket completely removed from the block? It doesn't take much if a speck of old gasket remains on the block.
doubt it's the switch ,but you never know until testing is done . Do you know what that is ? Automotive systems electrical testing , view a wiring diagram too see what all is involved in said circuit ,an using a DVOM - digital volt ohm meter to test B+ voltage an ground ? Looking at the wiring diagram for the blower motor circuit for your vehicle i see a blower motor relay , a blower motor resistor pack an the blower motor switch . The switch is just a path to ground . If it doesn't work on high speed i would suspect the blower motor relay . View the wiring diagram here

Obviously, it's an electrical problem. Electrical problems are many, yet they elude us when determing the CAUSE. You describe an INTERMITTENT OVERLOAD on the circuit... the challenge here is to determine WHICH circuit!
If you're not an electrician, then let an ELECTRICIAN troubleshoot it.
I, as an ELECTRICIAN, could teach you what you need to know to troubleshoot/diagnose electrical issues like this. However, this is not the forum for it. Have an electrician diagnose it. BEST ADVICE I CAN GIVE.
You got ripped off by the mechanic. A good mechanic can pinpoint the problem by using a scan tool. Take vehicle to autozone or similar and have it scanned for codes this will give you a idea what is wrong. I believe the problem is exhaust related because of the blinking light.
Pull the control panel out of the dash and see if the mode control vacuum switch has a good vacuum source or the switch itself leaks vacuum. The mode control is what moves the doors that diverts the air flow around to the vents, defrost and floor.
I recommend just get it back to the shop where the timing belt was done. They missed something. Might just be one spark plug wire not fastened correctly. But since that shop worked on it they are the most likely answer.
If they both went out at the same time, I would believe it's a connection problem. But, bulbs due have a limited life span, so it is not unlikely they can both go out within the same time. Take the bulbs out and check them carefully. Use gloves so you don't get any body oil on the bulbs.
